Wayne Klement sent the following photos and report:
I met about a dozen people coming down from Blackett's as I was going up this morning [W 9/30/2015] (one group of 5). All commented on the number of wasps at the end of Blackett's; 3 people said they had gotten stung.
Anne says: Right now, put a few anti-histamines in your hiking pack. An inhaler, too, if you have one. And don't hike alone.
