Punks out of Gym 8a+

The lower sectors are home to a significant colony of pigeons and bats (amongst other things). As such the environment around the sectors is not the healthiest. The left-hand sector (containing most of the better easy routes) is especially affected, where you will be standing on top of a 2cm thick carpet of pigeon guano. It is worth bearing in mind that this stuff can contain some very nasty diseases. Frequent hand sanitation, and/or masks, are highly recommended (not exactly a foreign prospect in these times!).
