sector calendar : 
Just a quick note:

This is not for public consumption.

The dates enclosed here are tentative sketches and locked in dates.  If you want to really know when an event is happening please go to the artist/company's website.  Do not book a night out with anyone you care about based on the events listed here.

Rules of use for this calendar:

Do not delete any items someone else has entered.

A "hold" on any given date, does not imply exclusive rights to that date, it is simply a request / warning to others to consider that they may be competing with your event should they choose to book on the same day.  My advice: call the other group and discuss it if you are concerned.
