My favorite shot glass collection is a Hard Rock Café collection I've been working on.
I do that too Kate. I have Kuala Lumpur, Kowloon (Hong Kong), Las Vegas, Orlando, Niagara Falls, Key West and London. I've been to all of those. When we were in London, we walked to it, with the couple we were with. They were so patient with me, because it was a long walk, to an out of the way place, not in a touristy area at all. One of my cousins is going to Denmark next month and said he will get me one from there..............if he remembers. How could he forget????
I have shot glasses from almost all of the Caribbean isles, given to me by friends who've been on cruises................I've never been there. Also Ireland, Wales, Scotland, England, Spain, Malaysia, Turkey, Singapore, Australia, New Zealand, Mexico, and all of the 50 States, but maybe not Alaska, can't remember. I have been to some of those places, but many were gifts.
I have them on display on a shelf in my dining area, but they won't all fit. Many are in boxes tucked away. About twice a year, I take them all down and wash them. Dust gets to be too much.
I also collect Christmas ornaments from places we've traveled to. That's a fairly recent collection.
