don't make me sing
if you're sometimes tempted when driving past the Arsht Center to get your Gleek on and have a night of theater, but then you remember it costs basically the weeks paycheck to snag some touring cast tickets- culturalconnection.org is a great resource for you.
The WLRN funded site hooks you up with same day tickets to shows at venues around the tri-county area.
Sure, you won't have time to plan ahead, but it's a great alternative to watching everything you stored on your TiVo throughout the week on a Friday night and their list of participating theaters is so long that anyone can find something.
