When southbound on I-5, I gas up in Vancouver, WA.
When northbound on I-5 (coming from California), I just gas up in Yreka.
I get to enjoy the fast service of pumping my own gas, paying at the pump, and scooting on out ASAP, and prices are generally lower.
On the few occasions when I failed to plan well ahead, I had to stop at an Oregon station, and it's always a pain in the butt. One time, there was only one attendant trying to pump gas on 8 stations, and it was busy... the poor fella is running around and he really did a lousy job keeping track of who was first. I had to wait about 10 minutes (no, I'm NOT kidding), but had little choice because I was running on fumes (I was about 10 miles from the Idaho border and thought I could make it... but decided I better not chance it).
I got out of my car, opened the gas tank, had my card ready to pay, even put the pump in my car. But that's all I could do... all the guy had to do was come over and actually pull the handle, lock it in place and then move on... I'd done everything else for him, but squeezing that trigger is the one thing I couldn't do.
Heaven forbid I actually initiate the process that begins the flow of gasoline! I don't know if a swarm of police, or black helicopers, would descend on me... But still, just putting the pump in my tank raised a few eyebrows among the local Oregonians who have been brainwashed the past few years...
It's sad when politicians decide to treat us all like idiots.
And yeah, on a trip in NJ last year, I did the same thing, gassing up in NY and Deleware on my trip through the wonderful "Garden State" (which was odd... looking around, NJ seemed more like the "concrete and asphalt state", but then I was trapped on the NJ turnpike for about 2 hours to go 5 miles).
Curiously, my friends from Oregon seem to have no problem whatsoever pumping their own gas when they go out of state.
