Barry,
Recon'd the coffee house, met one of the owners and discussed tomorrows plan.
The backdrop can be set-up in front and next to the coffee house (see pic). They are blocking off the parking places directly in front so you will have room to troop outside - inside, as you said, there won't be much room.
I am going to set-up chairs around back of the restaurant for you folks to take a break with water, towels, etc.
We will be there around 12:30 pm. I just don't see the banner you took over as being useful, its just too large, sorry
They say a lot of people are excited about the event tomorrow and expect a good turnout.
See ya there!
Phil
