Where I'm at in CA (along the central coast) never snows. The first time I ever saw snow was on a travel trip when I was about 15 yr. old.
Humorously, as it relates to md'ing: One time a buddy and I were on an md'ing trip to the high deserts of AZ and NV. We woke up in our hotel room, to find it had snowed outside during the night. But it was only an inch or so, so it wasn't enough to stop us from md'ing (you just kick the snow aside to dig your target, right ?). We picked a nearby park in this town, to hunt. After a few minutes, I isolated a target to dig, kicked the snow aside, and thrust my digger into the ground. I HAD NO IDEA GROUND FREEZES. Doh! Numb-nuts low-lander just had no concept of this.
We were stubborn anyhow, and chipped away at this target for the next 20 minutes, like chipping at solid ice. Finally got a nice merc. out of that hole, and promptly hit the freeway to get down to the lower desert level altitudes. Doh !
