I maintain a closed down K-Mart here in town; the islands in the parking lot, and a field on the side. City is "supposed" to take care of the rest. Anyway, doing the field today, made my first pass along the wall, got to the end which is the driveway going behind the building, and went to make my turn on the concrete and almost ran over this HUGE mass of bees. Never seen anything like it before.....they were just piled in a circle on the concrete.....about double the size of a large pizza. A few were buzzing around, but most were just climbing over each other, keeping in a fairly tight circle. WILD. Look closely at the grass near them, that's how close I came to running smack over them.....as I was turning I saw them and freaked out, hauled it outta' there at full speed! Grass actually hit them and a few of them buzzed me. Wow, close call! I'm highly allergic to top it all off.
