Depends how far you've got to go really. You just have to think that if you're going to be there for the day, that you have the distance to get there & home again, and the days rideout etc.
If you're happy with the miles etc, I know Stewie has said he'll be there for the day only, leaving from the Warrington area at some point.
EDIT: Sorry about that, it seems Stewie was pulling my leg about not being there Friday. I'll get my own back Stewie, just you wait
