My tuppenceworth on many of the points above.
Trail maintenance. I'd be up for some of this next year. Pretty sure I could round up some others too.
Parking charges. I'd be happy to see this if it all goes to trail maintenance.
Riding locally. The Pentlands are local to me. They are a few hundred yards from my front door and one of the main reasons we bought the house that we did.
I know trails turn to mud in winter. However this year it's different. It's the sheer scale of things. Even so-called "hard" paths are now being churned up. We've had plenty wet periods before that haven't caused this much damage.
Much as I want to see as many folk cycling as possible, there is a selfish bit of me that sort of hopes they will stick to the roads and leave the trails for me.
And finally, I'm just in from a nice ride on the road bike, and as expected, the Christmas excesses have taken their toll. Sooooooo slow!!
