Guerrilla Gardening

I saw this book in the Design Museum shop and it's currently on its way to me from Amazon. I really enjoy cooking, Ma has really got into growing vegetables over the past few years and I seem to include allotments in my architectural design work, so I want to get into growing stuff.
The one (pretty large) problem is that I have molluscophobia, an irrational fear of slugs and snail! I've had it as long as I remember, I have no idea where it has come from but apparently Steve Martin has it too!
Anyway the book gives ideas from growing food in old cans and even welly boots - well away from any slimy critters?! Can't wait to get started!
