USATF cancelled the Junior Olympics National Championships slated for late July in Jacksonville, FL because University of North Florida closed the campus. The facility is simply not available and the legal wrangling has commenced.
If NB moves the outdoors to Orlando, good on them! I have nothing against Greensboro but, in my experience with USATF JOs two years ago, it is equally hot and humid. The travel costs were pretty high and inconvenient (fly to Charlotte, rent car, drive 90 minutes, limited hotels, nothing for families to do on off days or to keep non-running siblings entertained, etc.). Orlando solves most of those issues. I wish that USATF would pick a permanent site or a short list of rotating sites with easy inexpensive air access, loads of hotels and Air BnB rentals across the pricing spectrum, and amenities for family travel. It's a hard sell to get working folks to pony up big money to get their kids to Hoover, AL or Sacramento, CA or Tallahassee, FL when a venue in Orlando, Los Angeles, NYC, D.C., or Chicago would provide a family vacation opportunity with theme parks, museums, and the like.
