Tried to get into San Antonio Creek in Dorington but the road is closed (private). C. murecose is supposed to be there. Also, at the White Pine end of the creek they've constructed a lake which may affect things. Drove up to Lake Alpine on rte 4 to see if any frogs there. Walked over a mi. of its bank but no luck. may be too much human activity. Stayed at Big Meadows Cpgd for nite. 7 July.
