I have to say we love Old Town (which is kind of small-town-tourist-trap-like but especially neat when the old car clubs go cruisin' on Sat. night) and the neighboring "Fun Spot". The go-carts, Nascar, & bungee are fun, but the newer G-Force Dragster ride ("World's Fastest Dragster ride") is amazing! Here's a link:
