The next holiday weekend is not one that involves days off. The Highway Patrol won’t be keeping traffic fatality numbers. The Water Patrol won’t be doing saturation enforcement on the lakes. August 5th through 7th is the second State Sales Tax Holiday, set up by the Legislature to give people a break in buying school supplies. More than half of Missouri’s counties are refusing to take part – as they did last year. Promoters of the holiday say it leads to increased business because shoppers buy non-exempt stuff while they’re buying the school supplies. The head of the Missouri Association of Counties, Dick Burke, says results were mixed last year. A University of Missouri study says shoppers saved $18-Million last year. Burke says $8-Million of that amount reduced city and county incomes for programs and services.
