after some of the things i have witnessed, i sincerely hope they are banned from all wild and scenic rivers. they are loud, dangerous to to the operator and others, cause a lot of bank erosion, 1 man in 20 has enough skill to run one safely. 1 man in 50 runs a jet with any courtesy. Since yours has a 90 i doubt our paths will ever cross, but if you go ripping through people in canoes trying to enjoy themselves, don't be surprised if they start throwing rocks.
