I love St. A's, probably one of the best big dune areas IMO. If it was only closer. I think if I ever get to retire I am going to be a (snow)Dune Bird. Hit Glamis in the winter and St A's & the Oregon dunes in the summer.
I have lived 100 miles south of St. Anthony for 55 years and I have never been to them. I have drove down the highway to Island park a million times but never made the turn. Mite have to do it sometime.
