Tried the AT&T WiFi coupon on the Mass Pike in Lee, MA in the service area parking lot where there was a participating McDonald's. Worked fine! A new technology actually working the way it's supposed to the first time. However, the McDonald's on the other side of the highway (coming home) was non-participating, so the joy is limited. Now I want the service added to my account for $1.99/mo like all the other AT&T DSL customers!
