alan, i'd say the best time to go to st. anthony's would be late may-mid to late june or else late august- early september. there are parts of the dune that are closed during winter - late spring. on duneguide.com you can find info on the dates that are closed. i wouldn't go there in mid summer, it can get really really hot. the only time i could go this year was july and it was very hot. we had to ride morn. and eve. and take afternoons off. by the way, @st. anthony you're only around 100 miles from Grand Teton Park and jackson hole WY. and around 150 miles from Yellowstone NP. the area around the dunes is real nice too, and REXBURG MOTORSPORTS is a real nice large dealership close to the dunes. also many places around rexburg sell race fuel by the 5 gal. bucket. hope the info overload helps you Alan, MADDOGGY
