Why or why, must it always rain for the Jefferson, WI swap meet and car show!?!

This is really a great venue, swap meet, car show...but.. for some unknown reason, the weather Gods always make it rain during the spring and fall shows!!

Its been dry up here for weeks, but sure enough, Jefferson draws near, and the rains showed up last night, through the night it poured with Tstorms, and now another batch of rain and tstorms has rolled through.. argh...

I guess another year of waddling through mud ponds and guessing whats underneath tarps...!
