Thats pretty easy for me. The southwest is almost perfect, I live in southern Arizona and its a beautiful place. At least in my town you have almost every example of nature within an hours drive. Like downtown areas? We have a pretty nice one, like neighborhoods from BEFORE mass housing came along? We have that, we even have those stupid housing developments if that happens to float your boat... Drive up to the mountains we even have a beautiful forest in this desert. There are many activities for outdoors men, from hiking through desert and seeing the amazing saguaro cactus, to mountain biking trails, and horseback trails. Its really an amazing place. The other day I was waiting for my mom to finish a doctors appointment and I decided to go for a quick drive, I followed one of the minor roads close to the mountains and with the foothills to my side and the mighty mountains in front of me, I didn't want to leave ;)
There is one downside however
Summer.... BY far the wost time of season ever to exist, go outside and stand in the shade and you'll start sweating like you ran a marathon... So to make it perfect get a summer home in the mountains, or in Alaska. ;D
