Here's what I suggest:
I think I can get the car to make the journey down to Kubla on Friday - so why don' I take the stuff and one person, then meet the others at the end of the BART line? It would save us on the rental. J0rn is supposed to be checking on rental costs for a big ol' van or some such which would also be ok I suppose, though I'll not have much time this week to get to a rental place and it sounds expensivo to me.
I am thinking of running a Forgotten Realms one-off dungeon crawl at the Con if you all are interested. Let me know.
