Thinking some more about this, I think that where I grew up also had an effect in turning me into the indoorsy type I am. In another thread here on SF where unhappy childhoods were being talked about, a member (don't remember who, sorry) replied that when things got bad at home, he'd leave the house and spend time in a nearby forest, that getting out into nature helped, IIRC. Well, the subdivision that I grew up in, being on the very bottom rung of the economic ladder that a subdivision could be, looked like this for too many years after it was built:

So, never anyone home since a lot of single parents--a lot of single fathers for some reason; guess that's why dad chose it, felt like he fitted in maybe--always at work, and just bare dirt yards in most of them since very few had the time or money to landscape.
And no matter which direction I walked in, after about a 45 min. walk, this is where I arrived:

Actually, the above pic's more interesting and pleasant than the real "shopping" near me; it was auto parts stores, car repair places, and liquor stores.
So nowhere within walking distance worth exploring, so I retreated into TV and books.
