Thanks to all for the input.
FWIW, the Baseball Trips can and do include side trips to local points of interest, so those suggestions are also welcome. (I’ve seen the Kennedy Space Center, Mount Rushmore, the Alamo, the Grand Canyon, and more, all on Baseball Trips!)
I’m getting together with my traveling buddy tomorrow night to make this year’s plan. I’ve got a draft of a workable itinerary that includes a night in Salt Lake and possibly a night in Ogden, but nothing is set in stone yet.
In case anyone’s interested, once we have a schedule I’ll probably post a thread listing all of the stops and soliciting further advice.
