UK Swap question 8

After much consideration (er...and much laziness):

What three items would you want with you on a desert island and why?

I was thinking the obvious things like Ipod and knitting, but if I was forced to only bring one ball of yarn and an Ipod with a limited amount of charge I think it would annoy me more when they ran out than if I didn't have them in the first place. So:

1. A Book. I know, as above I'm only allowed one book, but I should think the Complete Works of Shakespeare would take me a good while to get through.

2. Snorkel gear. If I can watch the fish, I'm happy. This would be SCUBA gear, but limited amounts of compressed air is as bad as limited yarn or batteries.

3. A mosquito net. Absolutely vital. I don't know what it is about my blood but I'm like catnip to the little buggers. *shudder

Oh, and I'd like to get off the island at some point. Please?
