This evening, my sister and I had prepared, with great anticipation, to have an adventure in the Roanoke City Library listening to tales of old...re: Moonshiners.
Upon wading through the usual afternoon downtown traffic, in 28 degree weather with a stiff tail wind pushing us down Jefferson Street, we promptly arrived at 4:45pm to the front door of our City Library to find a small notice on the front door stating the much anticipated event was being held at the Jackson Center...
There were about 15 people who were on the way up the walk to go to the same function , and of course they also had had no prior notice to a change in venue.

I am sorry to say this has caused me much concern in questions of my future visits to the Library.. Why was there no public notice made via the broadcasting system that the event had been changed,,?

Isn't there a way to advise the masses of a change in plans in future dates?
