What do you bring for 2 months on the road?

We're about 4 weeks away from starting the trip and we began to have this conversation, "What do you bring?"

Last year my two stuff sacks looked like this.  Surprisingly, I only wore 1/2 of these clothes.  That fuzzy thing at the top left of the photo is Toby sleeping.

This year, I figure that we're traveling south during the fall with Appalachian altitude during the first month, not Rocky Mountain altitude, and living in a rental the second month.  This altitude thinking is important, because it may be 50 on the flatland, but it's 30 on the mountain.  Also living in Savannah for a month means I can't get away with multiple tee shirts and jeans every day.

One of Ilze's friends suggested going to a resale shop in Savannah, then re donating the clothes after you leave

Here's the start of my packing.

As you can see socks and underwear figure prominently.  You also see a new Radius toothbrush and their Vegan floss.  Finally, when you're buying stuff you can ALWAYS buy more art supplies.
