That small hillclimb pictured by Steve is really cool although I'd probably quibble about the dogleg thrown into the middle of the underneath straight. Still, a neat track that's long enough for interest but small enough to have sort of a "bullring" feeling to it and Ogilvie is as good as they get for this sort of thing. The Orange is a classic track too and the "wiggles" or "esses" depending upon how they're done can add interest too. Either track could work.
Once you own the building, it seems as if you could cover the overhead pretty well and maybe pocket a little. For a semi-commercial operation, a 2-3 day/night with limited hours would be a problem especially with a rather rural setting with little or no opportunity for casual traffic. In that situation, all your traffic would be "destination" traffic (meaning they are going there intentionally and for a specific reason) I can't see that you'd ever recoup your investment but after that..........maybe not too bad.
For a "club" type arrangement, limited hours are no problem. You could just have a couple of set days (evenings?) whatever and that's that. Charging a "door" fee for those nights could work and that could be sort of your informal club meetings. You could have a set period of test and tune followed by a race at a set time. You might be able to have a membership "key" type set up as well depending I suppose upon how dedicated the guys get. Keep in mind that you need to get you race finished up early enough and have a set closing time so that the guys don't hang out too late and also get home to the family at a reasonable hour (happy wife = happy........)
FWIW and this is just IMO........I think a small (~~ 90'/lap) track is fine and generally speaking, slower cars are probably a better idea than faster ones. If you settle in on a particular class or two (or three) that are easily set up and maintained and supported by readily available product you can have enough variety for interest. Naturally, a club situation will be built around the meeting and social aspect of the group and the gathering and of course the racing is the finale.
Depending upon your setting and weather etc.....I always thought that a club that did a once a month "potluck" gathering might be cool to garner a sense of belonging. Just an idea but something like a Saturday.....open from what? 11-6 or something with a free race for the kidz and the wives with supplied cars or something (???) An available gas grill and a few picnic tables might make it a fun enough thing for the families to show up, hang out and feel less abandoned when dad "goes off to the track" on other nights.
Just spitballing but I sure hope it all works out for you.
