In general cost, travel time, difficulty of parking, etc. all affect optional travel. (And, also, just age and inclination.) I know I'm way less inclined to go into Boston/Cambridge for something in the evening for some combination of those reasons than I used to be. I can take commuter rail in for a day event but it's pretty much a non-starter for something in the evening.
