Yes, i should be available next Sat to act as guide on this one. 11am or thereabouts at Dunblane train station?
The Sheriffmuir climb from Dunblane is not too hard at all - honest! (no chevrons) and the Sheriffmuir Inn awaits for early revellers
For car drivers i'd suggest parking at the Wallace monument in Stirling and cycling up to Dunblane. Either via the easy (but busy) way via Bridge of Allan or warming up on the (lots of chevrons) climb over Sheriffmuir and down to Dunblane. Not for the faint hearted or under geared.
