The Montezuma Wildlife Refuge is opening up more open water habitat in 1600 acre Main Pool.  Some areas are so thick with cattails that it is not useful habitat for waterfowl.   Enter some big equipment to excavate cattail muck... mountains of it.    I recently got involved by way of driving the JCB dump truck as a volunteer.   The articulating aspect makes it fun to master, and sharing the narrow dirt road with tourists and birders, probably gives them a bit of concern.
