Now I know why I disagree with you all the time.
No -- you just think that you do
You have a preconception as to what is suburban -- but there are as many different types of suburban existance (just within Greater Boston) as there types of urban existance
I'm not a big fan of 2 acre zone lots, nor McMansions shoe-horned onto less than 10,000 sq. ft.
But I like the suburban lifestyle surrounding my house.
Within a 5 minute walk I can:
1) stroll to a small but nicely lanscaped park
2) take the dog to a few tens of acres of woods
3) take the dog / or myself or my bike to the Minuteman Bike / Pedestrian Trail and surrounding Great Meadows with hundreds of acres of semi-wilderness
4) eat or get takeout from a Mexican, Greek, Indian, Chinese, Pizza, sort of nouvelle American cuisine, and a Dunkin Donuts
5) bank, shop for furniture, do my laundry, late hours shop with food, newpapers and lottery tickets
6) 2 wine and beer shops
7) tailor, dry cleaner
8) bus to Alewife
Walk a bit further and I can be in Arlington Heights with more shops (Hardware, building supply, picture framing, etc.... and more restaurants and I can catch the regular every 10 minutes or so #77 bus (30 minutes to Harvard Sq.)
Get in my car and in 5 minutes (non rush-hour) I can be at Alewife, or Lexington Center; or on Rt-128 -- and in 30 minutes of driving or taking the T from Alewife I cab be in downtown Boston somewhat less to MIT
In less than an hour by car or by T I can be at Logan and within 9 hours of leaving my house in Frankfurt, Paris or London
I have neighbors with whom I regurlarly talk and sometimes share tools
Oh and I do have a small lawn, some vegetable plants and my wife gardens florally quite extensively
So what is wrong with that lifestyle -- why wouldn't it appeal to people in Brighton?
