I understand that the GPAC volunteers have been very busy coming up with a plan for the faciilty, and they've done a kick-ass job of it.
Now they've got to sell it to the public.
The lowest-hanging fruit is the moribund and frankly embarrassing Facebook page, which should be brought up to date and then maintained on a very regular basis.
Put up a link to this week's Council meeting. Then edit that footage into short bursts and link those, too (I know a highly-competent video editor who is available for volunteer work for the next several weeks).
Get a road show together -- you can use much of the same material, and get Keith Holliday to host it -- and start hitting the campaign trail.
Don't get caught in the downtown do-gooder bubble. It's a big city.
