Anyone from Minnesota who is familiar with the Paul Bunyan rail trail? I go Geocaching in my spare time and I noticed that the Paul Bunyan rail trail has a lot of caches hidden from Brainerd, MN heading north for 110 miles. What I would like to know the best time of the year to go out there. I would be walking the trail and camping along the way so I don't want to run into a lot of mosquitoes or other pest along the way.
