Brunswick balances Bowdoin's rotating population against families who've fished these waters for generations. Maine Street rooms fill with professors on sabbatical and lobstermen on shore leave—both want comedy, neither wants the other's. Topsham Crossing draws the commuters from Portland. Cook's Corner keeps it practical. Pleasant Street hosts the downtown energy. The comedy here navigates permanent and temporary simultaneously. Open mics demand reading which Brunswick showed up tonight. The comics who honor both the people passing through and the people who stayed find audiences on both sides of the divide.
