There are rumors afoot of an expo at the Tampa Convention Center April 9-10 2011.  Invnetor booths are $285.  The expected attendence is about 6000.  It appears to be a real event but is in planning stages now.  Today I talked to the organizer who assured me this will be a good show which combines Inventors, Investors, and franchises.  This may just be the show to attend.  Their website is expected to be up in about a week.  I will keep you posted.  In the mean time here is their brochure.
