I love the outdoors but I have to say that I like the outdoors a lot better when I'm bivvying! I just feel so much more in touch with nature - the smells, the sounds and the sights. But the thing I really like is the starry nights where you can actually watch the stars move. tents and so on have their place but for me, bivvying is best!!!!
I tend to use it on hills and mountains though rather than lowlands or woods. Main drawback is that its a bugger to get back into its pack with cold hands!!
