I will be hiking in the Glenn Canyon National Recreational Area this fall and ask you to match my pledge for miles hiked as measured by GPS. To help celebrate the lives of a great friend and colleague Dennis Ahnen and another science hero, Carl Sagan, I am going to try to raise "billions and billions". I am asking you to match me at $5/mile (inside hint: new shoes but knees are a year older!) That's a lot of miles but with your help, I can do it! How about $10 a mile?
I will be making my donations daily so you can follow along.
