In the Baylor hospital district in Dallas, all of the parking lots take these $1 vouchers that let you park as long as you want (multiple days in my experience) and they don't expire. Of course, you have to know they exist, but usually if you're there enough to have parking fees add up you'll have read the website or your doctor told you. I'm sure they still get lots of $ at the regular rate though, it's too easy to swipe a credit card. I wouldn't mind them jacking up the rates a bit like the TMC when rail comes in late 2009, hopefully enticing people to use that option. Jason WHOOPS, I see the vouchers are now $2. Still less than a Dart day pass though, which should change IMO.
