The only thing better than riding with your kids, is riding with your grandkids. When I retired I moved close to one of my sons so we could be part of grandkids life. Side benefit is being able to ride with grandkids and watch them go from trailer to Weehoo to tandem to their own bikes. It's like dejvu as I went through this with my boys (minus Weehoo). We now do an Annual Bike Trip with both my sons and their kids. Our last adventure was 4 days on the GAP with two tandems and a single pulling a Weehoo. Nothing better than riding with family.
