How about:

"Should the Jerk Cookout be at Horniman Gardens?
(Please read all 5 options carefully before voting)

1) Yes, definitely.
2) No, definitely not
3) Yes in principle, but with significantly improved parking and traffic management
4) No in principle, not without significantly improved parking and traffic management
5) Don't know/can't decide "

Do people think this will produce a more accurate reflection of forum views?

NB: It's only a first stab. My first thought was to only have 3 options, with the third being "Only if...." but then I thought that it would be too easy for both sides of the debate to claim the numbers from a third option phrased like that, and those who had voted that way might be split in what they would prefer if no traffic management solution could be found.

And while I don't personally mind publicly declaring my vote, given the heat in the main discussion others may not wish to, so I think the poll should certainly be anonymous.
