Myself and my roommates from our time at A&M have been traveling once each year since 2013 to watch the Astros play in a different ballpark.
Boston
Arlington
KC
Arizona
Colorado
New Arlington
Cleveland
Washington DC
Chicago (both White Sox & Cubs)
Baltimore
Pittsburgh

These are the parks we've been to so far. We missed a year or two with prior arrangements as well as Covid screwing things up. But, this year we're heading to Detroit to watch them play the Tigers in June.
Last year we went to a game in Baltimore that the Astros weren't playing in, and then we made our way over to Pittsburgh to watch the Astros play the Pirates.

Does anybody have recommendations on food or places to go in Detroit? We typically will do a small bit of sight-seeing, but for the most part we like to hang out in sports bars and play pool, darts, etc. It's just a nice getaway to hang out and watch some good baseball. Any recommendations would be appreciated.

Loved the stadium in Detroit, and the area around it has some entertainment. We went for a day game, so I can't speak to the nightlife (or safety after dark). There are some nice sports bars and a brewery nearby. A hockey bar is very close, but I seem to recall the others being a couple of blocks out past right center field (if that makes sense). Enjoy!
