We're thinking of making a trip from Portland to Saint Anthony for memorial weekend 2012. We've never been and are wondering if that's a good weekend to go. Also, where's the best place to stay with a 5th wheel? Elgin lake looks like it's the closest to all the fun. Is that where all the action goes down? Two of our bikes are on alcohol so we want to make sure we're not riding too far to get the dunes. Thanks for the input.
