I had a great time with my parents this past weekend! We were able to visit the UT Tower, which was recently reopened when the terror alert was lowered to yellow. I guess we were lucky - now that the nation is back to orange alert, the tower is closed again.
I just heard that part of the recent change to orange alert involves several areas of restricted airspace, which includes Disneyland and Walt Disney World! It's sobering to think that these measures are necessary, but it still feels good that the parks are being protected.
