I like to walk and hike and roller blade. Living near a trail makes it really easy to do those things.
I am a doctor, but my particular specialty lets me make my own hours to some extent. So, I can get out during the middle of the day for lunch with friends.
The scenery out here is spectacular. I grew up in Long Island, where it is only slightly hilly. Being able to see mountains every day when I get up makes it easier to enjoy the day.
The beach is only about 40 minutes from me, and I try to get over there most summer weekends.
