One of Clark County’s biggest annual food drives packed on a few pounds this year, with the Stamp Out Hunger campaign collecting more than 73 tons.The May 12 drive collected 146,564 pounds of food, said Don Young, the Clark County coordinator.That was 21,000 pounds more than the spring food drive’s 2017 haul.“It was a fantastic food drive,” Young said. “It was our best total in 15 or 20 years.”About 250 Postal Service employees took part, assisted by about 25 volunteers. Ten Clark County post offices served as collection hubs. The main Vancouver post office, 2700 Caples Ave., took in 60,417 pounds; the East Vancouver post office was right behind at 57,850 pounds.Stamp Out Hunger is a national food drive in its 26th year, organized by the National Letter Carriers Association.People are asked to leave a bag of nonperishable food by their mailbox on the second Saturday of May, and neighborhood letter carriers collect it during their mail routes.It’s the second-largest single-day food drive in Clark County, behind the fall Walk & Knock drive. The annual May collection makes a significant contribution to the Clark County Food Bank’s inventory — for a couple of reasons.Last year, food drives generated 548,202 pounds of food for the nonprofit; the 2017 Stamp Out Hunger event accounted for 125,535 pounds. Do the math, and almost 23 percent of the food that was donated in 2017 food drives came on that one Saturday in May, said Matt Edmonds, communications manager at the Clark County Food Bank.
