Although I went camping occasionally I did not start to camp a lot until I was around 30 years old and went on a couple Atikokan to Ely jaunts with my then widowed, 60 year old Dad.  The bug hit me then, I think I was old enough by then to have quit "running with the pack" of my peers.  Shortly after that I had my son and was home being Mom for about 10 years until he was old enough to be left with family and friends while I was gone for a week or so.  I finally got him on a 10 day trip when he graduated from high school, I took his two best buddies along too.  They were/are all techies and missed their computers a lot during the trip.  I think they had a good time in spite of it and now my son is glad to go for one or two trips a summer with me and sometimes one of his friends will come along too.  So I think there is still time for your kids to get the bug...
