I went to Busiek right after buying my mtn. bike. Clipped in at the range and headed West. First creek crossing I found myself upside down, in the creek, still clipped in after going over the bars. Water was a little deeper than I thought and the gravel was a LOT softer and deeper. I had a short and very scared mtn bike career. Decided my skeleton would prefer I stick to gravel roads and paved trails.
