Saturday morning's open-to-the-public scrimmage (11 a.m.) will be streamed at the official Islanders site.
If you can make it to the Coliseum, the way to secure $10* tickets (proceeds go to the Islanders Children's Foundation) ahead of time is through Ticketbastard, whose motto is, "Don't like that surcharge? We'll make it bigger." (In this case, the inconvenience fee tacked on is $2.25, while the price of actually getting your ticket if not using Will Call is another $1.75. ...And people said Pearl Jam were whiners?)
