If you go to work in Western WA, or Oregon or Alaska, please have sturdy raingear and good boots. I've seen some guys show up to work here in the Summer from elsewhere, and they bought Sorel boots to wear! They ended up working in those things all season. In May, I took out a team of people doing an audit. Two of them just disappeared off the hill, and were found back in their pickup with the heater going.
We also have people show up who don't realize what it is like to leave the nice warm vehicle, and have to go right into soaking wet huckleberry/vine maple/reprod. You get damp whether in raingear or not.
I know you are enthusiastic, but be prepared for reality. Steep, brushy, slick and often drizzly. A boot dryer is a good thing to have.
I was dreading working over here on the wet side. But one reason I grew to like it was that there wasn't the macho thing about how fast one could walk. I asked a guy why and he said that we care more about the question "can you survive and or not get hurt?" We were even told that we needed to slow down and take more time in our timber cruising--that was when the timber was large and extremely valuable.
Smokejumpers hate coming here on fires, and we once had a training session where we locals covered the ground and waited, and waited, for the eastside crew to show. They came driving up after deciding it was unsafe to go down the hillside that we did.
We don't work on that stuff too much anymore. Just come with the mindset that it isn't working in a park. Come with a good learning attitude, and be willing to adapt, and you'll do well. You'll maybe have some good stories to tell back home.
