I've refreshed my t-shirt collection with messages from the Alt NPS folks, from the Planetary Society, and from the Internet Archive. I'll have to see if the ACLU has shirts also. It's a small thing, but it's out there when I'm at the gym or in the store, and on occasion someone pauses and steps back to comment "great shirt." Message delivered. We need to not hide these interests when the boogeyman is in office. The only time I don't wear a message t-shirt is when I'm at work or giving a tour at the museum.
