Walking through the Hilton to the AD:Tech registration area, it was impossible to miss the AdBumb Booth Babes. Dressed in tight tops, pleated cheerleader skirts and high heels, the babes were promoting the AdBumb party Tuesday night, billed as the biggest social event of the conference. I thought booth babes were out of fashion at trade shows since the early '90s, at least outside of dental trade group gatherings and conferences for tort lawyers. Maybe they are, and I'm just a Neanderthal; I found myself picking up a pamphlet.
