It appears she was headed for the tree line but the wind was so strong it blew her off the trail.
Current conditions on Mt Washington are -31 with winds at 72mph. The one time I set out with two friends to do a similar route in winter, we never left our base camp. When the wind gusts sound like cannon shots and the trees are whistling and it's 25 below, I'm not going up there.....My buddy made six attempts at Mt Washington before he made it.
The Back Bay area of Boston is a filled-in area taken from the Charles River Basin. As a result the streets are street and the terrain is pretty flat. This big Oshkosh was at work there over the weekend.
There is an article in the Boston Herald contrasting Boston's response with Montreal. Montreal has about 4X the population and land area of Boston, but budgets $153 million compared to Boston's $18.5 million (actual spending this year is north of $30 million). It is 3.2% of their municipal budget, 4 1/2 times higher. Quebec also has a 9.9% sales tax on top of the national GST of 5%. One of the big challenges for Boston is that the state won't let the city add their own sales or other taxes. So that additional budget would come out of property owners as real estate tax. Personally I'm not interested in giving the city $30 million in extra revenue so commuters can park their Audis, so I hope there's a regional plan in place for next year.
