can you use lvs golf carts in the park..as Kansas statue says you can if the speed limit is posted at 40 mph or below

Yes

went camping last thurday,Friday and saturday..the camp host said nothing to me Thursday and Friday but Saturday this law guy stopped and said not to drive it on public roads in the park..the speed limits are 25 and 15 mph

Yes you can.

Haven't seen any being used, but i'm sure it's ok to do so...call the park office to check to be certain.

Yes you can use golf carts but the speed limit is not 40 mph in the park.
