PC Interesting Questions Swap - USA #7

You will be partnered up with 1 person to send a naked, written & stamped postcard. Postcard is SENDERS CHOICE but bonus if you can make it fit the question theme :)

This weeks question is: Where is the weirdest, most interesting place you've written a postcard/letter?

For example: I've written postcards in the air while flying on an airplane! The responses I got through postcrossing were amazing when they found out their postcards were written at 30,000ft in the air!

You may add more than one if you'd like (and if you have enough room!)
