Green Wedding

Hi everybody! Sarah Grace here to tell you my sister is getting married!! Woo Hoo! She and her former SO now feeantsy Brian are going to make it an official thang after being together like a hundred years. Of course, the jeep broke and they aint made of money, and were NOT planning anything fancy or costly anyway, something like a party in the back yard kind of celebration. I suggested a no gifts just bring a dish type invite, a byo (a) alcohol, (s) sleeping bag, [tent, air matress, pop up, etc.] if you plan to indulge much, and other than coming up with different dress ideas, (which green magic has not created yet) I am fresh out of green wedding party ideas. Any toss ins?
