There are several bars in the MIL area that are vape-friendly - we decended en masse on the Painted Parrot in 'stalls for one of our
vaping meets, they sell PV's (ok, admittedly, Blu's 8-o ) on the premisis.
I've seen the Blu's in numerous gas stations, as well, around here....and there is a B&M in 'tosa that you can drop in to pick up supplies if you're in serious need (if you let 'em know you're coming...)
TBH, I've only been challenged ONCE about vaping with 'em confusing it with a cigarette. As I was using a Prodigy V1 at the time (big, bulky, black...) all it really took was showing what I was using - the temptation was to ask: "does this LOOK like a cigarette???" but I behaved myself....for once
