If you’re in the area then why not get yourself over to the SingletrAction dig day happening at Stainburn (Nr. Otley, West Yorkshire) this Sunday (07/03/10). The descent line is being extended, there’ll be a fair bit of rock lumping, but you reap what you sow.
Usual drill – meet in the main car park at 10am, don’t forget to bring food, water,  appropriate clothing, gloves, etc. as it may be a little chilly!  There will be tools but if you have a spade or wheelbarrow it will come in handy.
Confirm your attendance at the dig though the nifty Facebook group.
You can read more about Singletraction and the work they do on their website.
He, he. Some of us ride CX bikes but we haven’t built a CX course in just the same way that some of us ride DH bikes but we haven’t built a DH course.
