Thanks girls, my DH is getting me a bit worried about things. Bless him. I'll make sure I pack lots of water in the rucksacks we'll be taking.

My friend (the Austrian one I'm visiting) only saw Sound of Music because I posted it to her for Christmas, otherwise it hasn't been released in Austria for some strange reason; luckily she loves it so we'll be doing lots of SoM related things. Yay!
