Caron Streibich and Mike Field told Southside Business Men’s Club members Wednesday about their missions. Streibich promotes Jax Truckies, the Facebook page promoting the more than two dozen food trucks that wheel their wares Downtown and elsewhere. Field organizes the JaxCashMob, which also has a Facebook page. The cash mob participants meet at a predetermined spot, then visit a chosen local retail store and spend $10-$20 there and then gather back at the first location, usually a restaurant or “watering hole.” The theme is to shop local.
