Hey Altered, sounds like a great idea of getting together, maybe meet up at a pizza joint/Bully's or something of the like! My husband is starting to come around as far as getting into it, actually it was his idea to go to SF to do some cachin! And it gets him off the couch!
Yeah, I'd say Portland and Vegas are polar opposites, you won't ever get the rainy weeks on end, that's for sure! However when it does rain in Vegas PEOPLE DIE! OMG!, just really watch out for other drivers, the yellow light runners, (this seems to be a big sport down there!)oh, and low lying roads, you should be OK!
I haven't yet cached in Portland (really want to hit the "original" cache!) but I have in Vegas, awesome GPS reception and a lot of great big urban caches! Compared to Reno, Vegas urban caches are the best! Actually that was probably the most fun I have ever had in Vegas since I'm not much of a gambler or fan of the strip but I go there occasionally because work sends me there
