Looking for a retirement business, I visited a entreprise expo in search for a good franchise opportunity. I saw food cart franchises that costs an arm and a leg but surprisingly low opportunities in the same industry also abound. And with gas prices becoming a big headache for most people nowadays, it was not surprising to see gas saving solutions among the hot businesses in the entire expo. I hope that people will take gas saving seriously. Most countries are dependent on oil imports and being able to control a country’s oil requirement is a good solution in the long term.
