So lots of people collect souvenirs such a fridge magnets, post cards and key rings. I personally like to collect shot glasses 🙂 You can get them in most places and there are usually a few designs to choose from.
Here’s my collection (so far!)
P.S. Please get in touch if you want to mail me a shot glass from your location and I’d be happy to send a souvenir back to you from Devon, England.
