About a dozen VIPs from around the country and abroad will be feted at a Vancouver dinner later this month, with private pilots flying in to greet them. Despite the high visibility of the Pearson Field gathering, which will include 200 other guests, the weekend visitors with impressive business credentials will keep a low profile. Their hosts assume that these investors and top-level corporate leaders would prefer anonymity as they check out the metro area’s potential as a place to do business.The business executive Fly In will take place Sept. 23-25, and the economic development organization Greater Portland Inc. expects a dozen or more top business executives to check out the region’s business opportunities. Beyond a small number of events such as the Pearson Field dinner, tours and activities will be personalized by local executives, who are acting as hosts to the high-level guests, says Susan Bladholm, the economic development organizations’s marketing vice president. Those committed so far are from the high-tech, software, green construction, solar, and venture capital industries. They’re coming both from the United States and Asia, Bladholm says.Ron Arp, a Clark County public affairs consultant also working on the event, says the Fly In is unusual in its ambition. It’s typical to invite business prospects one or two at a time rather than as a group, he says.
