The backcountry horseman aren't a bad group, but I heard the Enumclaw riders are downright nasty to bikers. Either way, thanks for the warning!
Sounds like it'll be funner than a barrel of monkeys. I've had the absolutely worse encounters with horses along 410. What is it with those weirdos out there? It makes me less and less enthusiastic about doing my part to quell the beast's instinct to freak out at the mere sight of another trail user. But I'm still playing the game with a fake smile while I'm dodging horse $hit.
