I already know to avoid entering the Cape on a Friday PM or leaving it on a Sunday PM, and to avoid the big cities at weekday rush hour.
Over the years, we've tried various routes, but they all seem to have become horribly unpredictable to the point of stoppages & detours -- especially our old favorite (I95-I295-NJTpk-GardenState-I87-I287-TappanZee-15-I95-I195-25-6). Last year, we took the northern route (70-81-84-90-495-25-6) mid-week but hit major bottlenecks three times along the way. Just hoping better timing might help. Thanks!
