When in airports always look for FREE wi-fi first!

So I am in Chicago. I flew in and sit for 3 hours. Anyways I fired up my Macbook (loving the 13 second boot to ready to use) and logged on to Boingo thinking it was the only "real" wifi here. After paying $5 (charging it to my T-mobile bill really) I heard an overheard announcement stating to set you SSID to Concourse for Wi-Fi access in the terminal. Sure enough I changed over. FREE! DOH! So word to the wise (and frugal) always try every hotspot before paying.
