Hmm, OK, I normally start a few days before, as I book in advance and we arrange a convenient day - as I'm only visiting regulars now my routine is pretty well worked out, and we can have a bit of an exchange of texts in advance of the actual punt. On the day itself it's off to work as normal (far too early in the morning), but includes a confirmation text sent at a convenient moment during the day, just to check all is OK. Then it's finish work and off home for a quick bite to eat, then shower and head off, I allow an hour to get there, as I arrive on foot (that last climb up the hill is done slowly!) I'll usually stop at a convenient seat with a good view, then around 5-10 minutes before I'm due (usually 7.30pm) I'll phone just to check everything is ready, and I head for the door.
And two hours or so later I'm happy and walking back down the hill again, on my way home. When I get there, I'll generally send a text to say thank you and goodnight. Yes, I know I'm a fluffy, but it works for me!
