Come on Aaron...lets think positive. I think the Mini Sliders and the new Modified things are kinda cool and would do well with the oval lovers out there. Thieir cheap enough in RTR form for nearly everyone to afford....you gotta get the new blood in before you can set the hook.
Seriously though Lee....what you really need to think about for downstairs is some overflow pit space.....your gonna need it once the KC guys catch on. I can see 75 entrie nights come next indoor season.
Oh yeah, get some signage up soon. Let everyone know that drives down Kansas Ave who you are and what you do. Think about getting some stickers of you shop logo made in a decent size....not really for placing on a rc car but big enough to be seen clearly on a full size car. Id fly on one the back glass of my truck...thats free advertisement that talks.
