ARE WE APPROACHING THE TIPPING POINT?

Even though gasoline prices fluctuate daily, they do so within a short range of pennies. But the price rise is inexorable. Prices are higher than a year ago, and will be higher a year from now--probably hit and stay around $6 a gallon for a while before climbing again. That figure--$6--is, according to many experts--the tipping point to major changes in our lifestyle. The question is--do we take a proactive stand now or wait until it's too late and circumstances are beyond our personal control? I would like your comments about the effects of rising gas prices.
