Last year's fall tour also included Baltimore and Reading, PA, not just NYC and Worcester. It was a pretty good mix of midwest and NE.
Also, the "east coast" is a big goddmaned area in the context of this discussion, especially this past tour. NYC got a lot of shows, four within a 90 minute drive or so (PNC, Bethel, Vibes and Jones). NYC area shows are not the only part of the east coast. For example, not everyone who can hit a Philly show can hit upstate NY summer shows (SPAC and Rochester are both hauls from Philly) or even the NYC area shows. Philly got a nice chunk this spring, only one local show this summer. (No complaints from me, but it leaves me wanting more). There was no DC area stop this past tour, it certainly wouldn't be "greedy" for folks in the Md/DC/NoVa corridor to want a stop there this fall. They've had a whopping one local show this year, two if you count Hampton. This summer there was one stop in New England proper outside of the Vibes appearance, and that is not for everyone and was more of a NYC area show. I'm not saying the East Coast "deserves" more shows or has been remotely slighted. But to paint the entire "east coast" with a broad brush is a little unfair given where the concentration of shows has been: NYC.
Bototm line in all of this however is that the band is going to play where it makes financial sense to do so. Not suggesting this is all a business decision, but don't kid yourself that its not impacted by those consideration. For a long, long time the formula for the northeast has been that the best way to keep the people coming is to keep feeding the beast with more shows. Seems to work. Other areas like the midweast, the approach has seemed to be the "absence makes the heart grow fonder" school of thought. Look at Fall tours toward the end of the GD: at best you'd get a stop in Ohio with anywhere from 12-15 shows in the Philly/NY/Boston I-95 corridor. Sometimes not even Ohio.
If you are in the uppr midwest and/or west coast and bumming about the east coast predominance, look at it this way: Heads in Texas, Arizona, NM, Missouri, Louisiana, (to name a few) would f'n kill for the access you've had to this band and the prior incarnations including P&F, 'Dog and even the latter day GD. So it could be worse
