Doesn't the rain and mud represent the WWII experience better than sun shine?!!!
The last year I vended there, the rain was just pouring. Some German re-enactors had purchased a heavy crate of some sort in the flea market, and four of them were carrying it up through the lanes. Near where I was standing resided a mud hole, and one of them went down in the hole. They all went down after that. I wish I had a camera as they were cursing with mad looks on their face, with mud all over themselves. For just a moment there, it was 1944 all over again.
