Watching the news this evening I was seeing all the reports on Veteran's Day Parades throughout the state and I got to thinking: just what is the deal with parades? It seems to be a holdover from small communities where nothing much ever happens. In that context it makes sense: half of us will dress up and march down the street, and the other half will stand on the sides watching us go by.
In brief, I don't really see the point.
I think it's different in the case of Mardi Gras and other such events, because then everybody joins in, and it's more like a street party, or a 'block dance'.
