An old fashioned Hoe Down

So, today was a pretty ordinary day. I went to lunch with two other lab members whom I didn't know too well but they talked in English, I talked in German, we talked about cultural differences and that was cool. After work though, walking around, I heard this music and then came into this plaza/area where this band was playing... some form of country or swing dancing music idk. There were even some people wearing cowboy hats (not pictured) so yeah. idk what was happening, but interesting stuff...
