If you’re coming on the 237 or 267 bus from Chiswick/Shepherd's Bush/Hammersmith way, the closest stop is Goat Wharf. I'm not sure of the current status of the bus stop, but if it's closed, the next stops aren't very far away.
I won't be there next Tuesday, but I'm sure the usual suspects will make an appearance. If you don't plan to be there Nic and Maggie, let me know.
Cheers,
Catharine
