Hi,
After reading about all of your relative's interests, it would really serve him in good stead to look elsewhere. My husband and I have yet to find many creative, intelligent people around our age down here (i.e. people age 25 and up) and the ones we have met, have all moved out of the area, after only having been here a year or two.
This post is not meant to harp on St. Mary's County. There are plenty of positive things about the area. Most of the people are indeed friendly, and there are more things to do in the summer...
My husband and I both come from an educated backgorund, and the atmosphere down here is not really one of education. For example, we moved here from Columbus, Ohio, where there are several large and small colleges, and over 65% of the population there is under the age of 35.
To graduate college and then come here was a huge shock. This area is family-friendly, but lacks the vitality and youthfulness of places where there is more emphasis on education.
We have lived here for almost 3 years, and are making plans to move as soon as my husband finishes his Master's degree program next fall.
The people we have met, that have similar interests--i.e. coffee shops, bookstores, culture, etc. have all left St. Mary's for the same reason--"It is sucking the life out of them."
The cost of living here, compared with somewhere like Columbus, is outrageous. Why pay over $230,000+ for a house when you receive no amenities in return? In other places, when you pay that much for a house, you receive the benefits of a good school system. Not in St. Mary's County. You may receive the benefits of having nice restaurants, museums, or movie theaters. Not in St, Mary's County. If you are a retiree looking for a place to call home, this may be the place for you. If you have small children and just want to have a nice space for them and be really involved in a neighborhood, then this is the place for you.
But you can find other, more cost-effective places to make these things happen.
I know I probably sound like a snob, but I really am not. These are my honest impressions of St. Mary's County after coming here from a completely different environment. I have met more than a few people here who have concurred with my observations. Wish your relative luck for me!
