I think your kids are smart enough to know better than that
And I agree with John, they are probably better off in here than on some teen site. And as long as you stay out of the pub, SB is pretty family friendly.
On a side note, does anyone else have a coleman camp stove(white gas kind). Mine is on loan and got left at the ranch, probably won't get it back by campout. I may just pick up another one, but hate to buy one new, they are my favorite garage sale purchase, I have probably bought at least half a dozen over the years, most of which I end up giving to friends($.75 for the stove, a few bucks for a service kit, an hour or two of my time, and I am ready to addict another one to the great outdoors
