Float the Boise River from Star to Middleton

Join us in exploring the Star-to-Middleton section of the Boise river, about 10 miles.  This trip is appropriate for small craft such as inflatable kayaks and canoes.  You must be able to ferry, eddy turn, and avoid snags/hazards.  There is at least one portage and areas where lifting/lining may be required.  No dogs, please.
