I want to hear tfltft's race report too, it is not up on her blog yet! Her twitter message said she was happy - 355th female is definately a great place.
Sarah, I lived in Nashville for about 8 years. Man, during the summer we would get one block from the house and our shorts would look like we just went swimming and our shoes would slosh ... it was pretty yucky sometimes. I remember though, most of the time fondly, that we did acclimate, and actually all my good 5K's (time-wise) were during the hot summer months.
