All sorts of opinions. Of course!
I grew up in NJ, and have never stopped missing some things about my natal state, but went to college elsewhere. My husband and I have lived in Dover for the past 30-some years. Obviously, we found that we could pursue our careers here, though we were lucky in this respect. A number of our friends have been less fortunate in terms of work, and have had to move on. Our children grew up here, were happy until high school, but didn't like it, I'm sorry to report, from then on.
Thirty years were enough for us, time for a change, and we were poised to move around a year ago, though hadn't decided where except for closer to family, but the housing market problems have discouraged us for now. We're getting the house ready, so we can launch ourselves quickly when the time comes, but that may not be for a a year or two. More?
What we don't like now that we're nearly seniors: not convenient to get to major airports. We don't like to drive to Philadelphia--as someone said, the northern DE traffic is reminiscent of the worst of LA, at times--and reliable airport shuttle / limo services don't seem to last here in Dover. We'll use one, kind of like it, and then it's gone. We drive to and fly out of BWI, but in summer that means figuring out whether we'll be able to get across the Bay Bridges, going and returning, with all the beach traffic. This has been a common complaint among our friends.
If you're young, you may not mind driving to cities a couple hours distant, for whatever it is you seek, but my husband and I both advise you to give this some thought if you want somewhere to settle as you get older, and especially if most or all the family you want to spend time with are far away. This is one of the main criticisms I've heard over and over again from many here in Delaware. They do feel isolated, at least in central and southern Delaware, and those still living in northern Delaware are finding some aspects of their situation more difficult to cope with.
On the other hand, we've found an abundance of pleasant places and people, friendly people

, in this state. It may not, quoting jskirwin, be the prettiest place to live, but some of it is beautiful. You have to open your eyes to find treasure! I'm hoping to see some photos posted here. If not, I'm going to have figure out how to post a few of my own.
