On my usual route home from work, I pass a Cingular billboard on I-271 south (just before exit 23) proclaiming Cingular has the "fewest dropped calls" of any cell carrier in the nation. This claim might or might not be true. Either way, I find the billboard's placement quite amusing, as Cingular's cell coverage is spotty on that stretch of 271, and my phone drops calls there all of the time. I would have thought Cingular would be more careful not to advertise where its ad claims would be so inconsistent with consumer experience.
