That's exactly what I did when I asked for my tower and Tennadyne log periodic beam. I had a party, invited the HOA board, plied them with food and liquor, let their kids swim in my pool, explained that I'd be happy to pass traffic in the event of the "big one" then humorously pointed out all the other 'violations' throughout the plan. There were many of them. You did exactly what you needed to do to exempt yourself from a a portion of a freely signed covenant. I had no problems and I didn't ask for the permission of congress. They also let me park my boat in the side yard. Amazing what a little personal diplomacy can accomplish. Good for you!
