Hello fabbers!

Sorry for the silence lately--I've been out in the field (the rainforest) over the past week, where the style is "comfortable with a side of DEET insect repellant".

I"m in a bit of a panic, though, and was hoping you might have some advice for me. I thought I was leaving Australia in 5-6 weeks--enough time to plot out what I have, what I need, ID wardrobe holes, and make a shopping list. Well, due to governments working efficiently, I will actually be leaving in about 3 weeks. I don't feel ready at all! My schedule is roughly this:

2 more weeks in Sydney, where it is Spring-Summer. I have a few events to attend still (concerts, 2 evening/indoor, one afternoon/outdoor).
1 week in far north queensland. Field grubbies and DEET.
1-2 days in Sydney
5 days in Texas (November. Haven't checked the weather yet)
5 days in North Carolina (again, no weather knowledge)
Scotland (this is mid-november)

One of my plans for time in the US is to go shopping. But I thought I had more time to plan and figure out what I thought I might need. Do I just toss what I have in my suitcase and hope for the best? I'm taking pictures and an inventory of what I have as I pack, but I"m not sure if that's enough, since I really don't have time to start building winter capsules at this point.

I did a bit of a random shop last year when I moved here, and that didn't really work. I need more of a plan than that. Help?
