I'm currently fighting with bamboo from my neighbors yard where they planted it for a privacy wall. I think it's a losing battle. In a few more years I can at least probably save some money by selling my lawn tractor and replacing it with a good machete.

Might make for a cool yard actually, except that it dies every winter so in the spring it's just a big dead mess of dried stalks (not to mention a fire hazard) until the new growth starts in.

With great power comes Awesome irresponsibility.
