Wear rubber boots or runners that you don’t mind getting wet. Bring coveralls, a helmet that you are able to fit with head light and a head light, if you can get one.  Bill has some extras that he will bring.  Flexible gloves, if you have them. A change of shoes and socks. A lunch.  Not essential, but whoever has a walkie talkie, or VHF radio, please bring it with charged batteries.  The more we have of these the better.
