You are entirely welcome - I look forward to my own version of this rash for the coming month - our state fair opens Thursday, and I will be there for at least 4 days, walking on concrete, asphalt & dust. (Some think environmental bacteria or allergens can contribute as well.)

Now that I think about it, my Dad was a letter carrier, walking 5 miles every day on his route; he had this on his legs (above the sock line) for years.
