Thanks for the advise and I am posting in the other section recommended too. We're not looking at being "exact" when it comes to scale, I just didn't want it to look "silly".
The grandstands have been the biggest challenge. I've found them in HO Scale and in 1:32 Scale. So, I know one will be quite a bit smaller. Which would you go with? Since it will be "played" with, I would prefer a larger scale then HO but at the same time, don't want to go "too" big and look way out of scale for the cars.
I can already tell I'm going to be spending some money on Ebay to get this the way I want, and that's fine. It's the only gift the child has requested and he's always "cautious" w/ his cars.
I want to do building, bleachers, people, concessions, garbage cans, etc. I honestly don't mind spending the money, I just want it to look "right"!
