That is what kids are for. Then they have kids so you have 12 year old grandkids to play with.
One warning though. Actually two.
1) watch out how much weight you put on the tube and then whip around, when tube hits end of rope it may flip you and atv(been there, done that)
2) the first time your daughter sees you and the grandkids (or your wife and your kids) wipe out the tube and atv in a cloud of snow... she may raise hell until you give up for the day
If possible send mom and grandma shopping or something. That way you have a chance to get home from the hospital with the new cast and be settled on the couch before they get home. If you call them on the way to the hospital they will be pissed that you ruined shopping and it could have been one of the kids.
None of the kids or grandkids have been hurt beyond a few bumps and bruises but I have broken my wrist and ankle on the pasture slalom.
Good advice, I'm only 25 and only been married for about 4 months, but soon enough I will be able to utilize this advice.
My EDC: Handcuffs, Bandana, and Ball Gag.
If I'm ever at a party and the cops come to arrest people. Ill blindfold myself, throw the ball gag in, handcuff my hands, and hide in a closet. Police never arrest hostages!
