its worth coming up to PMB and using the course they made for the Downhill World Cup. its still standing, i ride it petty often (but on a FS Bike, not as a Downhill rider mind you). There are lots of sections you can practise on, then ride up and do them again. its at Cascades mall, park your car and you have a great track right there!
sections of it have come into disrepair and they've been cutting down some of the trees so a whole section is unridable right now. if you want more details PM me and i'd be happy to help you out!
