How about saving $120 a week just by giving up your driving freedoms and car pooling? Hey, if you are looking to save money then this is a no brainer. CNN just featured an article which really drives home just how important car pooling can be in today's era of outrageous gas prices.
"Robert Gilliland didn't think much about carpooling until gas prices got out of control. Now, he's happy to trade his motoring freedom for $120 in weekly savings. Gilliland found one rider through the classifieds Web site Craigslist and another using the carpool-matching service eRideShare.com."
Although car pooling might not be for everyone, if you hours are not consistent or if you have to stay late from time to time and there are also safety concerns. If can hook up with co-workers, neighborous or friends, all the better.
