JMHO - - - - - Regardless of people's ages, I think you'll find the newest areas will have more neighborhood activities and "automatic socializing". Why? Because everyone there (regardless of their age) is in the same boat - they're all new to the Village they're in and are all excited and wanting to meet everyone around them. Not so in many cases when you move into a Village that has existed for a while - say several years. Most people there have been settled in for a while and have found/made friends both in the neighborhood and via their other activities. Not to say that there's nothing that goes on in their Village from a social standpoint. But you might find that, since everyone's not in the same boat as you (new to the neighborhood), your expectations might not be met. We bought a home in Duval around 2 years ago and found this to be the case. We're snowflakes so that might have a little bit of a bearing on it......but I really don't think so. From Day One, we knocked on doors to introduce ourselves to our neighbors, have spoken/waved to everyone who goes by, and so on. EVERYONE without exception has been very nice and extremely friendly........but for the most part, we'd never know that if we weren't the ones stepping up to initiate the interaction.
Wherever you choose to buy will be great!
