I migrated to COM and White Mountain BMW pretty early as my preferred clubs for one reason:  tone.  With both of those clubs the tenor was more warm.  Old timers were willing to lend a hand and the powers that be were less aloof.  To give you a trite, yet meaningful example, the call to the grid:

At COM and White Mountain the call to the grid is usually something like this:   "run group three, the track is green for you in 15 minutes... if you want to run please come to the grid."

as opposed to Boston which is more like "Run group three, come to grid NOW, and I mean NOW! I mean RIGHT STINKIN' NOW!!"  whadaevah

At COM especially the thought was that we are here to push our cars to the limit and the occasional trespass over that limit was not a smear on our moral character.

At White mountain the road to instructorship was clearly laid out. I do not want to do everything that is required for them, but at least it was clear.   I am still not sure what I have to do to become a Boston instructor (COM is pretty murky too)

Boston is often the last club to announce dates for the driving season. 

I have never understood why brand new students are not paired with an advanced student.  Instructors are busy and don't have the time to really introduce the new student to the event.  If you want new students to come back they need to feel welcome socially.  I suggest the way to get advanced students to agree is give newbies and their advanced student mentor free, reserved garage space.  What would really be interesting is a database that could track first timer return rate. 

Seems to me that Boston is competing with all the other driving options in the following categories:   Overall price, value (price per lap), location, scheduling, quality of instruction, maintenance of challenge as students progress,  and camaraderie. Might be best to decide to be the best in just a few of the categories.
