Before I started dental school, Emilia and I biked from Pittsburgh to Washington DC on the Greater Allegheny Passage (GAP) Trail and the C&O Canal Towpath Trail. It took us 5 days to cover the 335 miles by bike, hauling camping gear and food. The C&O Canal Towpath portion of the trip was extremely wet and muddy and much of our bike componentry got corroded/fried. One such element being the first to go, our bike chains! As a memoire to our trip I punched out the pins (rivets) and nailed the chain to our a piece of wood that I finished, stained, and applied epoxy to.
