Aren't they great?
I've just got back from a couple of hours in the Surrey hills - Three Amigos, Golden Nugget, Abba Zabba, etc for anyone who's interested - and it was fabulous. Just riding at my own pace on dry-ish trails, going for flow rather than flat out speed.
Saw two badgers, one of which was completely oblivious and bumbled along right beside me for about 15 ft before realising I was there, as well as a heron and numerous bunnies and bats.
It's rides like this that remind me how beautiful the countryside is round here and what a lucky sod I am to be able to enjoy it on my bike while everyone else is sitting at home watching telly.
