There are worse things to do on a nice mountain in the summertime then get drunk, not that I have actually done any of them. For that matter, have I ever gotten drunk on a mountain in the summertime? I’ve been to SCA events on mountains, so I’ve almost certainly gotten drunk on one once; but whether I’ve done it in the summertime is another question.
Anyway, it sounds more like the bees are doing the… apiary?… equivalent of chewing locoweed, which I have not ever done. That entire phytotoxin thing.
