Ever wonder how billboard ads get there? How chain restaurants grow? You needn't be a prospective real-estate investor, in short, to savor Dooner's accomplishments in property-based enterprises. (And if you want real-estate basics, you'll have to look elsewhere anyhow.) Dooner, a recovered alcoholic (it takes character to succeed in business), got his start as a field auditor for the Outdoor Advertising Association. On his agenda is everything from attracting national advertisers and leasing (or optioning) likely locations through zoning-code compliance. The top consideration--""number 100 showing"": the total number of boards needed to reach 100 percent of a market's population within a 24-hour period. In metropolitan Atlanta, Dooner and his associates made do with 112 high-traffic sites--thereby undercutting a Ted Turner company which required advertisers to take 128. Another line of endeavor was the now-flourishing Hen House restaurant chain, which Dooner started from scratch. Initially, the key was tying up unused land next to service stations on well-traveled Midwestern roads; eventually, Dooner was invited into lucrative partnerships with Standard Oil of Indiana and Sunoco. He has also done well buying, refurbishing, and reselling old Holiday Inn motels. For those inspired to try, he provides hints on sizing up properties and clear explanations of the complex financing techniques he utilized. Mostly, though, this is an offside success saga for the roadside-strip generation.
