Bill, everything sounds great so far.
But I would like to make a suggestion....
When we go on our annual guided pheasent hunt there are several sponsers that donate door prizes. We put everyones name in a hat, and draw for specific prizes. IE....you know what you're getting when your name is drawn. When you get your prize, there is a thank you note and card already addressed to the sponser that donated that prize. You sign the card and put a little note in it thanking the sponser for your individual gift. The cards are all taken up after, and mailed at the same time.
I could probably pick up a pack of thank you cards, but I don't have the info to go ahead and put the addresses on the envelopes for each door prize. If you would PM or email me the list of individual prizes, and who donated them, I'll get the envelopes made up and we'll hand out a card with each prize.
If this sounds like a good idea to you let me know.
