The San Marcos City Council is in the horns of a dilemma as it attempts to write an ordinance for zoning sexually oriented businesses (SOBs) within the city. Should the city zone specifically for SOBs, which, according to city officials, is likely to doom that part of town to blight and high crime? Or should the city follow the more standard municipal practice of allowing SOBs in areas zones for industry, which would open them to a section of town that stands to benefit from about $175 million in public investment and includes some of the city’s heaviest employers?
