Hi Holly!
Yes, I discovered Georgia yesterday and am gonna sit here for a spell (at beautiful Crooked River State Park). I love that non-site-specific camping feature, too!
While in VA, I made it through plenty of nights in the teens and 20s and a number of days that didn't get out of the 30s with all my plumbing intact, thanks for asking! I am happy to know that I can easily camp in those conditions, but I did not want to have to drive in icy or snowy weather, so it was definitely time to head south.
I've been following your blog and am happy you made it to Oregon, congratulations! Your posts and pictures of your travels through the Southwestern states and California have been really enjoyable. Thanks for sharing your travels so well, and good luck getting settled into a Northwestern Winter.
Carol
