We were there on Friday too, I had my red ribbon on, but like you all I didn't see anyone else with a red ribbon either.
The show was amazing, the first one I have gone too.
We are just a little over an hour from Lancaster and spend a lot of time camping there, or sometimes just for the day. Have gone to Weavers many times, not Friday though, but didn't know about the "back barn", will have to look for it next time. We also go to Goods, next to Shady Maple Smorgasboard and to a fabric outlet in Churchtown, just a mile or so from Shady Maple, if you know where that is.
Good to know we shared the experience, even if we didn't meet, maybe next time.
