These nut bars have migrated from all over the country to the northwest....

How much you wanna bet these particular nut bars are from California?

Entirely possible...The whole west coast is infected....

I doubt it's "eco-terrorists". Instead is most likely a feud of sorts. On some of the busier rivers there is enmity on the kayaker's side against rafters.

The kayakers like to hang out on certain rapids and surf their boats in the holes. When a raft comes along the kayaks have to move out of the way or they get run over.

I know of one case where a kayaker took out his survival knife and slashed a raft after it pinned him against a rock.

No, they are probably natice Oregonians. Most of the militant groups are.
