The city of LA's Carol Armstrong offers river history to tour participants.
My buddy Zack Behrens over at KCET reports that the LA River will this summer accommodate nine times as many kayaking tours as last year. From KCET's Confluences blog:
Trips will run through September 29, and a start date for this summer's program will be announced shortly, according to Mike Mena, spokesperson for the L.A. Conservation Corps. This season they will partner with a number of groups, including Friends of the Los Angeles River, to make this happen.
Something about river kayaking in California makes me quote Ratty from "Wind in the Willows" and--at least mentally--wax rhapsodic about summer river rambles in Ben Lomond, and year round treasure-trash hauls in the San Francisquito Creek.
But here I stop just to quote the great Matt Eddy, in advising you about getting down into the LA River. "Never don't go."
