At some point after 30 (a traditional and pathetic "once upon a time" beginning for my generation), I started collecting snow globes. I thought it would be interesting collecting a piece of Americana that is traditional enough to be found literally everywhere, even outside the country, yet each globe is different in every town. You can even find them in places where it does not snow. Sad and fascinating.
By the way, all irony is lost, because I actually think these are cool. ALso note: no globe could be too cheap (as you can see here with shitty Santa), with Goodwill's discarded gems and Vegas-style tourist centers practically giving them away.
After a while friends and family saw I had a few and they started to buy me globes on their own trips.
