IOS Silent Auction Items Needed

At the 2012 IOS Conference at The Morton Arboretum, our first IOS silent auction was held. The funds raised were set aside to help students attend future IOS Conferences, and in 2018 they were used to help five students attend the Conference at UC Davis. The proceeds from the auction at Davis will allow us to help out even more students attend the upcoming Conference at Las Cruces, New Mexico in August. We will once again hold a silent auction in Las Cruces and I would like to ask members if anyone has items they would be willing to donate. Items should ideally be oak related; jewelry, books, clothing, seedlings, etc. have been big hits in the past. We recommend that these items be small enough to pack easily in luggage, but larger items are welcome as well. Please contact Ryan Russell at russellry76@yahoo.com if you have items you would like to donate. Thank you for your consideration and generosity!
