Will be heading from Denver to the Upper Peninsula of Michigan in late June. Plan on spending about six days making the trip. Drive a day, fish a day. Am presently planning my route and am considering traveling the first day to the Black Hills of South Dakota and then on to Whitewater State Park in MN. These are just preliminary plans. I was wondering if anyone had any suggestions or other ideas on places to river fish for trout on the way. Thanks for any help. Fish on!
