Sounds like you guys have been having some good rides up at thrunton. I joined the trail builders a year and a half ago now and am glad that people are enjoying the stuff we've been working on.
Just wanted to echo Ians points really, I don't think anyone wants to see thrunton move more towards a trail centre with mass usage (indeed the people who dug some of the original trails might jump off one of the crags) so its fair enough to respect some of the original builders wishes and try and maintain the best possible relationship with the FC through keeping the trails fairly low key. I'm sure people have been heading up since before I was probably born but I think the newer trails in the trees will generally not last half as well as some of the classic crags stuff?
On the flipside a small random bunch of us meet at the carpark the first Sunday of each month to maintain/improve and build new stuff, it would be great to see some of you come along if you can make it.
I think its definitely noticeable that a lot more people are now riding the trails and I think most of our work this year will be trying to make sure they dont get washed out so the more hands the better!
I'm sure this type of discussion has been had many times over about other local woods, its difficult to try and have your 2p without sounding like a selfish trail builder who wants their work to themselves!
Feel free to get in touch if you'd like any more info about the dig days.
