Thank you, Pete, I understand now: Friday through Sunday, July 11-13.

The only thing is that the IAC calendar looks like this.  It's not exactly "wrong", just misleading.  If you click the "2 more" pulldown you can see CL Scale on Friday & Saturday.  But if you just read it and don't pull down the pull downs you will be two days late.

Yes Paul, this IAC calendar is not very helpful in this case.  Let me know if you have any questions.
