My non scientific survey of traffic shows that the bridges are crowded on most days, even weekdays at the usual times and a month ago that really wasn't the case. Many are probably day trippers but (unfortunately from my point of view) the restaurants in Falmouth have been very crowded particularly on the weekends. I drive 151 a lot when I'm down there and that road is busy from North Falmouth to Mashpee on any day of the week.
