Well my girlfriend is a botanist, and her passion is spending week end exploring all those SSSIs in and around our county. So each time she saw some nice rare plants or potential ground for rare plants trashed by bike tyres, she has the same feeling as you when you discovered that your favorite trail has been closed down or trashed by bulldozer, trial bikes, 4×4,etc… I had probably ridden SSSI in the past, but I now accept I was wrong and people have other passion than just mountain biking.
