My parents weren't the outdoors type. I joined the Boy Scouts when I was 11 and have been outdoors every since.
Hell I can't even work in an office for two days in a row.
A few years back my company decided I should be a project manager, that lasted less than a month, they told me to take my laptop and get my ass back out in the field. Good thing about them is that they pay you based more on longevity and performance rather than job title.
I can remember camping in canvas tents that you didn't touch when it was raining. About the same time as I joined BSA there was a guy that owned the service station on the corner in our neighborhood, he would load a up a few of us neighborhood hellions and take us out camping for a weekend at the local lake. He had a pickup camper and a tent trailer, used to haul 4 or 5 of us about once a month, grand times.
I started my two kids camping when they were 5 and 6, we tried to go once a month. Kept that up until they went off to college. My daughter lives in a cabin in the MA woods and my son lives in Boston. Both still love the outdoors. I currently live on 40 acres surrounded by suburgatory, but they will have to pay me a lot to move.
