Why put the time capsules from those two eras back? Isn’t that the idea of a time capsule... to allow future generations to get a little glimpse of their era? If anything, put the contents of both of them on display in the Massachusetts State House for visitors to view and appreciate... and put another time capsule, from today, in the cornerstone so someone can open it up 100 years from now and get an idea of things we thought would interest future generations from our time.
