Don's the first I've known to take note of this.
After today's Don and Doug webcast, Don shared an observation with me.
In the on-going waves of protests around the country, roving bands of demonstrators have successfully managed to block tunnels, bridges and key highways.
Some of these shut-downs are being carried out with only a handful of protesters.
Almost anyone who commutes probably passes through some kind of bottleneck on a regular basis.
Interstates may seem free flowing, but blocking just two to four lanes can hold thousands of travelers hostage.
How at risk is your commute?
