Lol...wow that is cool!! You're not playing around. I would probably do the same thing if I had three kids under 6. I don't think it's extreme at all. It's a lot cheaper than paying for door ding and paint repairs.
Lol fly a flag toohow about i dig a moat?
very similar idea.....can you electrify it?I used swimming pool safety fence. A little hard to see but the car is covered on the right side of the fence. I isolated the entire side of the garage with the fence and the only thing over there is a cabinet with detailing supplies and a hose. I just open one section and climb in and back her out. If I need the whole garage I just pull the posts and roll it up. The two sections cost about $200 total and they are pretty strong I hit it with the corner of my plow pretty good and it held up great didn't even rip.
