I think there is one in Bartlesville in OK. i want to make one in Salina OK. and and i want to make it huge. if i get any people commenting about it i may go through with it. there is a lot of land with natural dips and ramps that i could turn into a sweet 1/5 scale track. let me know what anyone around Salina thinks. its about a 45 minute drive from tulsa.
