Those are great shots!
I really wish you fiendish people would stop posting amazing crops from K20D -- I have the urge to sell off my K200D just to get the K20D's resolution (and viewfinder..and lens dial ins..and advance controls)
Oh, and believe it or not, those bees aren't going to sting you unless you step on them or swat at them -- they're more interested in the nectar
I know the feeling though - I've had a reaction to a wasp sting, though I think it's because I was very young. I was given a shot kit in case of future stings - you might check with your doctor to carry one around, they should be very inexpensive and could save your life!
