We'll be in Halifax Friday October 11th on the Emerald Princess. After looking around for a good tour, I came across this one:

It sounds exceptionally thorough (except missing Peggy's Cove which is a long drive with a dozen tour buses there so I'm OK missing that).
We are the first to sign up and need a few more people for the tour. Please consider if you'll be in Halifax that day!
