I'm a California Native
I just live with rednecks.
1. You can't pump your own gas in Oregon.
2. There'* a State Police station at the Hwy20 exit in Albany (the next exit after your hotel).
3. If your radar goes nuts at Hwy34/I-5, don't sweat it. There'* a microwave communications corridor through there. 34, however, is heavily patrolled.
4. Have fun in the Terwilliger curves in Portland
They're fun at night when there'* no traffic.
I'll get more info on the go-karts for you sometime this week at the latest.
