Melting/falling ice

Dan pointed out on the call yesterday that when doing field work at the BAO in the vicinity of the guy wires (like at the lidar super-site or the UTD 200S location), we should be aware of the risks of falling ice/snow from guywires and from the tower itself. Hard hats are currently available at the building at the base of the tower, and some hard hats will be moved to the visitor center, as well.
