Does this really rule out the Wanderers Grounds? After all, the clubhouse could be incorporated into a stadium and rugby could be played in a new stadium. The clubhouse could display the history of rugby and football in Nova Scotia.
The stadium could be built with low rise stands so that it doesn't impose on the Public Gardens. Both Detroit (Ford Field
http://en.wikipedia.org/wiki/Ford_Field ) and Baltimore (Camden Yards
http://en.wikipedia.org/wiki/Oriole_Park_at_Camden_Yards ) have found ways to incorporate historic buildings into their stadiums). We are thinking about a much smaller capacity stadium in Halifax (but not an uninteresting stadium). Halifax could also do something unique just like Detroit and Baltimore have done.
