We were in Ankeny Labor Day weekend for the Midwest Tandem Rally (300+ teams) and rode the High Trestle twice. First Friday evening riding from Madrid to Woodward and back and then again on Sunday as part of a 62 mile ride. Since I have some fear of heights, we didn't stop out on the bridge to take a look but we did ride the length of it three times. Amazing bridge and trail. And, lots and lots of trails in the Des Moines area.
