We bought a new house last June. There was a neglected cherry tree in the
back yard that we cut down. The whole yard was so negleted that we have
HUNDREDS (at least) of volunteer cherry trees on the back lawn. They get
cut when we mow the lawn, but it is very painful to step on one with bare
feet. We have 2 young kids, and they're always running around out there in
bare feet.

Any ideas on how to get rid of them?!
