I'll continue to keep an eye out for it in Estes. Ryan and I went to get it the last day the water was up and it was already gone. We scouted the whole V section and down to Drake. There is a chance that it got caught in one of the sievy sections or the second waterfall. When the water goes down again, I'll try to get down there and check again.
Though it would be a pain, have you tried posting lost boat in any of the papers near there? Estes, Drake, Loveland?
Have you talked to the Fire Department and SAR crews??
I'll send a message to the owner of the Mountain Shop in Estes and have them ask around along with put up a poster with the boat, color, and your name/number if thats ok?
