Future vacation destination suggestions ? I'll hit a few places I've been for sporting events, all of them fun in their own ways:
Fenway Park, Boston, MA in 1999 - fantastic place to watch a ballgame, though with COVID it'd be impossible, you are elbow to elbow with everybody and right down on the action.
Providence Park, Portland, OR - it has been newly renovated and with PSU getting kicked out for Timbers games, Davis no longer gets to play downtown against the Vikings. Crazy local fan base, they love the Timbers, and as one might expect, things can get a little bit heated in the crowd.
@ Boise State, great fans, tailgating top notch
@ Oregon, obnoxious fans, but you get to meet a lot of folks who are "famous" in UO and Nike circles, the Duck fanbase is more widespread than most know.
Daytona Speedway, Daytona, FL - a cathedral to racing, it's a total culture going to a NASCAR event. A very long party.
Wrigley Field, Chicago - another surviving tradition of neighborhood ballparks, fiercely loyal and hilarious, fanbase finally got that World Series recently, and Bill Murray cried.
@ Fargodome, North Dakota. A true college town, surrounded by not a ton of humans, but Morehead, MN is right next door. The fan base there is very loyal, and they show up, very friendly place, and cold.
@ Missoula - Montana fanbase has football embedded in their culture, a real way of life, party friendly, visitor friendly, and very spirited.
Baseball Hall of Fame - Cooperstown, NY, like a Field of Dreams reel, very, very pastime nostalgic. Awesome place to visit.
Not sports related, but in travelling around the country I think my favorite city visited was Savannah, GA. Very unique community...a lot of history dating back to the Revolutionary and Civil War times, some amazing stories are out there in the mainstream. Great place for St. Patrick's Day (2nd biggest get together outside of Boston) and Halloween -- Savannah is embedded deep in voodoo country...and they love to dress up and drink, even when there's no real occasion for it, let alone Halloween.
