I forgot to mention that throwing rice is traditional and has ancient symbolism, but birds often peck at the rice after everyone has left and it is not digestable for most of them. So, in lieu of rice, have your Maid of Honor help you to bundle up bird seed into some of that sheer netting and tie them off with ribbon strips that will reflect your color scheme.
Firefighter color schemes: red/yellow; orange/yellow; flourescent green/yellow/red.........hehehehe!!!! AND, instead of having dainty little shoes, you could wear your firefighting boots! Omigawd, I need to stop, now!
