I'm probably only going to visit Nova Scotia once in this life (too many places left I want to see!), and after reading quite a bit of advice here and elsewhere, I'm left with one question. I'm flying into Halifax from Texas in May, I've only got a week, and this is probably the only visit I'll ever make. So, should I go south to the lighthouse trail or north to Cape Breton? Which visit is more a "bucket list" sort of experience?
