Arlin Keith and Terry Flanagan have the chance to open this track next year. We would like to get your thoughts to help us see what you would like to happen. You can reply on here or call Arlin 573 518 4485 or Terry 573 783 0207. Thanks Terry
 
We are wanting to start with pure street, 4 cylinder class, go cart class and try to start an actual pure street class that is complete stock. We want to start with these classes and build up from here. We hope to get helpful responses from everybody who wants to help make this track a fun and successful place to be at. There is nothing set in stone about everything we are going to, so that is why I hope to hear from you to give us your thoughts on how things would work best for everybody. Thanks
 
Is Sunday at all possible if you start early enough, say 4:00 or 5:00? I know the track's near the town so going late on Sunday's wouldn't be possible, but I think you could do well since you'd be the only track around running Sundays.
 
My opinion is not that major but I think the pro-4 class would do fine. If u r wanting a pure street class use the same rules as bellville or peavley run. I personally think the rock is to big for the go-carts. It is great to see the younger generation racing and we all start somewhere. But there is competition not to far away on friday night. Maybe a sportsman class. There are several of those cars out there for sale rite now. Just my 2 cents. Thanks.
 
The Sunday idea is one I've always had for that track as well I was thinking even a 2-4 start time somewhere in there. That way as mind blower said you're not trying tto compete with tracks that are established with in 35 miles of you. Would really like to see this track up again.
 
I hope you guys can get the track going again. Friday nights was always a bit difficult to get down that way from up north. Sunday night wouldn't be a bad idea but one thing you have to take into consideration is that "The Rock" is in the middle of about 4 churchs. There might be complaints about Sunday night racing. Now if you had church nights and invited the congragations out for $5.00 admission. And have the Pastor's give the invocation before the races. The noise complaints could be smoothed over. Just an idea.

This is a great idea, hopefully they would give this a shot. Could not hurt could it?????
 
I think you need a Mod. class, you have 20 plus B mods at Farmington and the
A Mods always have the best races and put on a good show. Pure streets and Pro 4 would be the other 2 classes. I hope it works out there is a lot of people that would run there before Doe Run and Farmington, just one thing you have to prove pay the cars and stay open.

Im with the basic class set up you have mentioned.. AS always, if we run friday, have the sense NOT to run the same classes as Doe Run..Its just common sense.. You WILL pull half a class, and they will pull the other half.. That hurts all involved..and makes a sorry show for the fans..Keep in mind that they are the reason we are there to race, and without them, the track will not stay open!!! No butts in the bleachers=no money. Also... keep in contact with Keith Adamson.. He may open Poplar Bluff next season...He raced here for a few years, and is a good and knowledgeable person.. You may be able to do some back to back shows with him..I support the Purestock class!! I have a stock roller ready for a cage. I will not however put my time and money into it without a commitment to open, and set rules..It will take me most of the winter to build, so knowing something soon, is the only way Ill build it.. I bought a car to run in the purestock class, and the track didnt open this year..I was frustrated, but luckily I sold it.. I have a purestreet, b-mod, vintage, ministock, and a purestock that can be built.. I NEED to know which way to go!! I can make plans to race at the rock, and would love to.. I have no doubt it will be great!! But if its December before I hear anything, I will have already put a car together to go elsewhere..
 
I think the classes atleast be A mods, and defantley B mods because the car counts at farmington are big in that class. Then farmington pure streets and ive heard alot of pro 4 guys say they wanted to come race at fredmo if it opened. also the actual pure stock class would be good if the rules made it cheap enough to buy a regular pure street and put a STOCK motor in it with rodchester carbs. just my opionion.
 
They ask everyone what classes we would like to see, but on there face book it says that there gonna run karts, 4cylinders and purestreets only. and when we all said mods they said no..
 
I say we go back to what worked!!!
