Three facts:
1. If you run over a small stick while mowing with a reel mower, the reel mower will stop on its tracks and you'll probably do a flip over it and get hurt. With a gasoline powered mower, you wouldn't even notice the stick was there. The power of gasoline can't be denied.
2. This thread quickly went from lawn care advice to gun control arguments...WTF?
3. Navy Mike is the one and only, true authority here regarding lawn care advice. So everyone else just hush.
