Nice map! I'm currently in southern Wisconsin and we're suffering as well; but we can take it! You know it's dern cold when the dogs (who normally just ramble along) are rushing their walk in the mornings, LOL!
But by about 2pm on Thursday afternoon I will be in the lower left of your map...the coast of Mexico where it's in the 80's. Toes in the sand, Corona in the hand, Baby!
Poor pups. I take it, they are staying at home.;-)
Sounds like fun, don't forget to turn over every 20 minutes.. and use sun block :-)
