Chris,

Congratulations... nice work. I especially was fond of Sleeping Beauty Kudzu
—brought back fond memories of South Carolina... Kudzu, Civil War statues,
kudzu, grits, nail styling salons, Confederate flags, mosquitoes, humidity,
scorpions, Civil War statues, copperheads, hair styling salons, humidity, grits,
wild dog packs, humidity, kudzu on Civil War Statues, black widow spiders,
Civil War statues, Confederate flags...

Oh, Sam & Sandy!

hehehehehe
