I went down the lower Kinni w a large group, and that was a huge mistake. I had my own kayak, so I "bought" shuttle service from these guys to get me back to my car at Glen Park. What I didn't know is the group I was with mostly rented kayaks from them (I made the assumption most people would have their own 'yaks) and when we landed at the State Park, me and two other guys who brought their own kayaks had to wait 3 hours for shuttle service back. (I wish I were exaggerating here)The large group really threw off the schedule and the mix of rentals and shuttles needed for personal kayaks was messed up. They were apologetic and I understand this was an out-of-the-ordinary experience. But still, I half expected my $15 back just for a way to apologize. Moral of the story - small groups are best - especially since this is a fast moving, narrow river where side-by-side convo is hard sometimes.
