ARE THERE ANY DECENT HOTELS NEAR BIG SCRUB?
no, there all about a good 40 mins away at least, or at least the ones I saw that is
Try the Fox Den Inn in Umatilla that is about the closest one. Its about 15 minutes away from scrub.
Do you really want to spend the money on a hotel when the only place you can ride is the power lines. Better bring all identification you will need it. Those rangers are always stopping everyone.
