Setting up local celebrations across the country is apparently what America250 is about, but Trump wanted to do his own thing and so he played up the “Freedom250” events that he largely controls as the official celebration instead.
Fun fact about the Freedom250 fair: states are not reimbursed in any way for their participation, which as you can imagine is very expensive, so many of them simply decided not to show up because it was not worth it.

I think that you greatly overestimate the number of days the average American has to take off.
