first signs of construction

The new elephant exhibit begins construction in about two months, but it is an addition in a field behind the rhinos with no access. So the first step is to start on the visitor pathway, which will cut through the end of the rhino exhibit. I was surprised (saddened, disgusted) at how far into the rhino yard it is - they cut it almost in half. I am hoping this is temporary until the path is done - the sign does say it is for construction vehicles. However the one keeper and docent I asked about it seem to think it is permanent. If so, this is a HUGE mistake. It is GREAT to have more room for elephants, but why give less room for rhinos? That is a big step backwards. I sincerely hope this new fenceline is not permanent.
