Are y'all still trying to do this trip?
DC is implementing a vaccine mandate for those over 12 that's going to make it fairly difficult for a group of unvaccinated 15-18 year olds to do a lot of stuff. Yeah, you can stick to stuff in NoVa like that concert but in DC, that'll be tough.
I don't have anything specific along the lines of a Travis Tritt concert but y'all obviously need to be aware of the mandate ahead of the trip.
