Professional climber, filmmaker, and funny-guy Timmy O’Neill is on the road this week hosting a “David Letterman meets David Brower” multimedia show he calls the Environmental Action Tour. Tonight, he’ll be in Portland, Ore., at the Hollywood Theatre with special guest Kipchoge Spencer (of InterActivist and really-awesome-name fame).

E.A.T. will then head to San Fran and Asheville, N.C., next week. All the shows start at 7 p.m. and tickets are $8, with proceeds benefitting Patagonia’s 1% for the Planet campaign.

O’Neill’s motto? Putting the “mental” in environmental since 1969. Hmm … should be an interesting show.
