When you donate to our Wings & Rivets project at an event we are attending, your on-site donation entitles you to a free gift. Please select the gift you would like to receive and donate the amount for that gift. The full amount of your donation will go directly to our Wings & Rivets Project. After donating, you may receive a request for a "tip" to help cover the costs of processing your donation. We do not receive any portion of the tip, as that amount goes directly to the folks at Zeffy.com who manage our donations at no charge to us. A "tip" is not required, but is greatly appreciated.
