You can have my garden when you pry it from my cold, dead fingers

A recent letter from the friendly neighborhood homeowners association:

On behalf of your association's Board of Directors, we are writing to advise you that your property may be in violation of the governing deed restrictions of the association which may be corrected as follows:

Upon receipt of this letter, you will need to remove your vegetable garden. This is a violation of Association Documents.
...
[emphasis mine]

Oh, yeah, you read it right. Remove my vegetable garden. Over my dead body.

In this day of pressing climate concerns, rising fuel and food prices and global eco-consciousness, with every other house in the neighborhood being foreclosed on or for rent, they're seriously going to try to get me to take out a vegetable garden? We're not talking about a tacky statue of a gnome (sorry gnome-lovers) or a pink flamingo on a stick. These are well maintained living plants providing food for my family. See here for some pics.

They're going to have a hell of a fight on their hands. I'm generally very non-confrontational. After my last house, I've deliberately avoided participating in the HOA. Now they're going to discover why you don't want to bring stupidity to my doorstep. Don't make me angry. You wouldn't like me when I'm angry.

I'll post more when I'm not so pissed off and can establish a rational strategy.
