I'm sure most of you have seen these roadway signs - No Hazardous Cargo. I know it includes propane, but what do you do when traveling through Boston and "Stella", our GPS, named such because I sometimes yell at it, directs us to Sumner Tunnel and just before it's too late, we both see the 12' 6" height sign (we're 13' 3")? Well, you suck it up and look for a truck route.
We found one, but it wound us around to take one of two options - Sumner Tunnel, again, or 13' 6" height restrictions (okay for us), but no hazardous cargo! We took option number two.
We dutifully pulled up to the toll booth, paid our toll and were about to depart when the collector inquired what our rig was. In fact, he asked: "Whattya got in there? Horses?". No, I replied, it's a camper. Uh oh..."You got propane?" Yup, we replied.
With no place to go and no propane allowed in the tunnels, we were told to wait by the side of the highway for the State Police who would escort us through the tunnel. We waited about 5 minutes, and sure enough, here comes a trooper who asked us why we were in the predicament we found ourselves in. I explained and he amicably told us to follow him after a very mild admonishment by telling us we should have taken route such and such.
We followed, and he took us through one tunnel, but exited before the next ones and took us through various streets and turns to get us on I-93; he had his lights on and people did wonder why we were following!
As my grandmother often says, "it was an adventure!"
