I think he means that that race site has too many rules...
As for surfaces, I don't know if I have 10x10 area of carpet. Most of my house is hardwood, and other people will have different surfaces too. Should we make a rule that the race has to be on carpet, hardwood, or cement? If we did, some people would have to sit out on some races. Maybe it should just be where ever you have room.
I've got 4 tracks drawn up. Sorry for the huge pictuers. LMK if you have anymore designs, these were the only ones I could come up with for a 10x10 area. Lane widths are 2.5 feet.
I only drew them in paint, so they arn't semitrical at all, but you get the idea.
