because for many regionals a good percentage of the teams attending are local:

no chartered bus
no hotel rooms
the students go home at night - less expense for meals.

If you cancelled a local regional, many of those teams could not afford to travel to another city.

I had to check for myself: Cleveland, Pittsburgh and Rochester-NY all on the same weekend. Wow! Thats gonna make teams from our area really spread out this year for 2nd regionals!
