AGH! I would have loved to have known that ORANGE ST was going to be totally blocked up today!

Is there a place on this site or another that announces these events? A city calendar?

There's a calendar on the lancaster city website, events aren't always updated or added, there's also the calendar of events at LancasterArts.......
This festival/parade is something that happens every year, I saw it advertised online osmewhere but I can't remember what website I was at - It very well could of been the LNP site.
