If there was no COVID - Captiva Florida to take the fishing trip I was supposed to take back in early April. I had an awesome long weekend booked with my Dad and my son to go charter fishing for some redfish, snook, tarpon, grouper, etc. Had an awesome VRBO right on the bay, and my favorite charter captain lined up. Things started locking down a few weeks before we were supposed to go, and I cancelled last minute. Glad I did as flights back stopped the day before we were supposed to return, so we'd have likely been stuck.
I was looking forward to that trip for MONTHS, and then it just got taken away. I'm literally still bitter to this day.
