Hmmmmm. Within a 2 hr. drive of Portland? And they are required to be "secinic"??? Would a "scenic" one be acceptable??? (sorry, couldn't resist that...)
This is an interesting question. Within 2 hrs. of Portland, huh? I guess it's gonna depend on how fast a guy drives, in some cases....
There are tracks at Abany, Goldendale, WA, Madras, Longview, Riverdale, Sandy, Washougal, WA, Woodland, WA, Prineville, & PIR that I know of. I'm not sure how many of them fall within that 2 hour drive requirement. There may be more tracks closer that I'm missing, but I'm not sure how many of them are scenic.
For "Scenic" tracks, I'm thinkin' I have to go to the track I first went to in 1979 in Boise, Idaho. The track that the Owyhee Motorcycle Club had off of Bogus Basin road back then (haven't gotten to return for about 20+ yrs., so I'm not sure if it's still open or not...) used to be an awesome track. I swear, from the top of that hill they had there, a person could see the Rocky Mountains.... And eastern Oregon.... I believe that downhill went somewhere around 450 feet, if I recall correctly...
Anyway, good luck findin' what you're lookin' for. Shouldn't be too hard around here... Are you lookin' for good photographic opportunities, or good ridin'?
