I found a ground nest of yellow jackets the hard way today while cutting the lawn (I'm not allergic, but it hurt like H and still does) - reminded me of a few Algonquin instances, but also reminded me to check and make sure that I have Benadryl (pill and cream) in the canoeing first aid kit. It is one of those things that is easy to overlook but is a key item to have on hand, just thought it was worth mentioning.
