Good Saturday evening, MetaFilter! This week, jessamyn wants to know "What is underground where you are?" [more inside]
FreeStuffFilter: I just looked at my subscription-paid Weather Underground page and noticed that the WU is letting me send free 1-year memberships to anybody I choose. I've already sent these to my family, and the WU keeps giving me more, so if anybody wants one, ping me and I'll send you one, until I run out or WU decides I've sent enough.
