Ya know, I don't remember any swelling or itching from the bumble bee back stabbing, though. That's kinda odd.
Speaking of bees and motorcycles. I was coming back from SEFF (radio control airplane show) over in south central Georgia a few years ago (before I started keeping bees). I was just northeast of Georgetown, GA coming back to Alabama when I went down into a bottom where a small bridge was (two hills on either side naturally). I was on a jeep and as I neared the bridge I saw a cloud of "something" covering the entire road over the bridge. When I hit the bridge honey bees splattered all over the jeep....a swarm! Well, I started up the hill when a guy on a motorcycle (yelp :shock:) topped the hill headed towards the bridge. I hung my arm out trying to waving him down and flashed my lights at him...he kept going. I slowed down enough to see him approach the bridge, see his brake lights come on, and see him continue on up the opposite hill. I don't know if he got stung or not (good chance he did) but he maintained the bike in the proper orientation (shiny side up). My jeep was plastered with goo so I stopped in Eufaula and washed the honey and bee parts off...I can only imagine how that motorcyclist was coated!!!
