First snow and Second Language Acquisition?

So the mountains around Vanadzor have been getting snow on them on and off for the last couple weeks, but it looks like the one mountain outside my window has some snow that is here to stay.

Luckily it is snow that I can see but haven't experienced yet.  It's been cold and rainy here the last few days, but that isn't so bad as I see some people in really cold parts already posting pictures with inches of snow on the street.

Also, this is for my TESOL PCMIers, I've been meaning to take this picture for months, and finally I had my camera out and about and I passed this building that had this tag:

SLA!  The first thing that came to my head was of course Second Language Acquisition.  I haven't been able to figure out what the original intent would be.  Any guesses anyone?
