Oil: a market response?
The local paper ran an editorial today encouraging the use of mass transit and noting that "Snohomish County's Community Transit has hundreds of unofficial billboards posted across the county - at every gas station. With prices breaching $3 per gallon, there is no better advertisement for mass transit."
For the past several years, I've increasingly walked or used the bus to get where I need to go. I did initially feel inconvenienced at having to look up bus schedules and get to the bus stop on time. That quickly gave way to a perception of increased convenience, as I got out in the fresh air more, didn't have to worry about traffic congestion, and could read while I rode. Besides, the economics clearly favored the bus: the $2.50 fare to Seattle wouldn't buy the gallon of gas I'd probably use, and I'd still have to pay for wear and tear on the car and for parking in the city.
