Havre de Grace Mayor Bill Martin relishes being viewed as someone who is willing to think outside the box, so to speak. As long as he doesn't stray too far, that can be a good thing.The mayor has said he would like Havre de Grace to get a trolley system, not in the traditional sense of street cars running on tracks, powered through an overhead line or below street cable, but one of those ersatz bus/trolley (or is it trolley/bus) systems that cater to visitors. In keeping with his decision to buy electric vehicles, the mayor says these trolley/buses should be electric.Well, so far that sounds great. The mayor says the trolleys ought to heighten the experience of visiting Havre de Grace. And, oh by the way, the state will pay for it through its community development grants program.So, what's not to like about this plan? Plenty, unfortunately.Martin gives as an example, Rock Hall, where there is a functioning "trolley" system in the Eastern Shore town that is extremely popular with boaters from all over the Middle Atlantic region and beyond.We'd be more concerned, however, that the proposed Havre de Grace trolley system ends up like the one then-mayor William Donald Schaefer installed in Baltimore's Inner Harbor in the 1980s during the area's nescient redevelopment. The system of gas fueled buses, dolled up to look like old-time trolleys, was a money loser from the start. The city eventually turned it over to a private company to run, with the same result.We're certainly for anything that enhances a visit to Havre de Grace, which already can hold its own with many of the waterfront tourist venues along the Chesapeake. The risk of setting up a trolley system presents a risk – and cost – that frankly isn't worth the reward. These vehicles cost money to operate, they break down, there's going to be minimal demand during the weekdays and near zero from December to March.More sensible is the city's plan to apply for similar state grants to pay for more way finding signage to help visitors find things. Another much more productive use of state financial resources – and ultimately the city's – might be a waterfront public Wi-Fi system, something many towns Havre de Grace's size have considered.The main visitors spots in Havre de Grace are within a relatively compact area along the water. If city officials took anything away from this summer's Pokemon Go craze, it's that people of all ages will indeed walk around to get to things that stoke their curiosity, albeit with a little prodding sometimes.We don't believe having a trolley system is a deal-maker for Havre de Grace and might indeed prove to be a pig in a poke. Keep it in the box.
