I like Central PA but traffic along I-81 & I-83 is really starting to be a bit of a mess. We have traveled to all 48 states & we still like this area better than most places we have visited. I love to visit other areas but I wouldn't want to live in most of those areas. It seems we have the "best of all worlds" here. Four seasons but winter isn't super nasty and summer only has 15 or 20 days over 90 degrees (most years). Nice amount of rain to keep plants and grass alive yet not raining all the time. ETC
Plenty of decent paying jobs yet housing cost are not bad. Plenty of good food, places to visit, etc.
