7. Flying
Yes, the commercial airline industry has taken a hit but we continue to fly business and first class as write-offs when just about any meetings and conferences can be done via telecommuting in the year 2010. No one wants to see jets grounded for good, but there was a time when flying was a privilege, a luxury. But now, with the frequency of boarding a Greyhound bus, we round-trip it on Southwest, figuring the fuel cost outweighs a six hour drive, any day. Meanwhile, we await that cost-effective jet biofuel the Pentagon announced it is developing.
