That's the way in seems to be in the HighSierra. There was one Memorial weekend hike in Tuolumne Meadows when I opened the car door and realized we weren't going anywhere until we were coated with bug repellent. But I've been up there or similar places 15-20 other times with no bug issues at all. We had no bug issues in Yellowstone, Waterton or Glacier NP's on our June 2013 trip either.admin":2gczo9os said:You may well have a point about the shorter life cycle in the high alpine areas.
