It seems my fate involves moving frequently - I hope this next one is it for me, and that future moves will be in the local area. Ideally I will meet someone and settle down. ;) As far as employment opportunities, cultural attractions, entertainment and so on, the Washington DC/Baltimore metropolitan area will be hard to beat... and so I hope to stay. I'll be busy exploring the area for a long time!
I typically don't miss places as much as people. That being said, I wound up liking central Florida much more than I thought I would. There is other stuff to do besides theme parks, honest. The weather is pretty good for running and biking year round, and I took advantage. Kennedy Space Center is nearby - I got tickets to see a launch once, but it was delayed and I couldn't make it. I enjoyed kayaking and canoeing, and the occasional airboat ride, even if that is more on the touristy side of things. I'm not a huge beach goer, but I went a few times and had a great time with surfing lessons. I visited Key West with my family, but never did explore the rest of the state much at all. No trips to the panhandle or Jacksonville or even St. Augustine, no stop in Miami, and only two or three quick visits to Tampa.
But it comes down to the people I knew, and I will miss them. I got lucky finding a great/active biking club and running club and made several close friends. The good news is flights are short and cheap - 2 hours and about $200 if purchased in advance. I know I will be back in Florida twice in November - once for a friend's wedding, and a second time for a half marathon.
My blog helped keep in touch with friends when I moved from Washington. But now, most of the people I knew in Florida are all on Facebook so I guess that will be the new way to keep in touch.
