Dave Giegerich just keeps cranking them out. Here's a couple more from him:
Hi Nick, I'm at it again. Last Wednesday gravel Metric #7 on the FatBike, just a easy roll, on the back roads on NE Iowa. Sunday on 4/1/12 I rode metric #8 on the CX. a out and back. Tried to work the return half of the trip on my upper end of heart rate, cause I needed quick slack'n the pace.
Here's a picture of the cemetery in Dyersville.
Thanks for the chase
