Landscapers can be screamed at. They can even be fired.

Deer on the other hand are forever... I have several deer that have decided that my squash plants are very tasty, and they like to stand around the garden delicately eating the leaves off of them. Then when they need a change of taste they start on the basil and peas. They are completely avoiding my tomato jungle.

I would consider flouting a few state hunting laws, except for the fact that there is a neighbor's house in line with the garden and the direction I would be shooting. Maybe paintballs... :)
