Before hitting the highway this weekend, Fairfax residents might want to fuel up at Schmitz Exxon in Tysons Corner: In celebration of its 50th anniversary, owner Eric Schmitz is discounting gas by 50 cents a gallon, as well as serving up hot dogs and other road-trip goodies, from about 1 to 3 p.m. Friday.

A regular unleaded gallon of gas averages $2.21 in Virginia, according to a recent AAA survey.

Schmitz said he will also raffle off a year's worth of free gas, worth up to $2,000, at his gas station at 8526 Leesburg Pike near Spring Hill Road.

"We're celebrating the fact that we're one of the few businesses operating in Tysons Corner for 50 years," said Schmitz, who estimates he sells 16,000 to 18,000 gallons of gas a day at his location near Tysons Corner Center.

Healthy Doses of Medicaid

Management consulting firms with significant operations in Fairfax County scored big in vying for state Medicaid contracts over the past week.

Accenture, which has more than 2,000 employees in Reston, said it won a five-year, $840 million contract to operate the Medicaid eligibility and enrollment systems for Texas.

A few days later, on July 11, Electronic Data Systems Corp., which has a large government solutions division in Herndon, said it won a seven-year, $73 million contract to manage Oregon's Medicaid system. "This is all about serving the health care providers and the taxpayers who foot the bill," said EDS spokesman Bill Ritz.

Angels in Northern Virginia

The July issue of Inc. magazine highlights the Washington Dinner Club, the Northern Virginia venture capital fund headed by John May, in a profile of angel investors.

The Washington Dinner Club typically invests $500,000 to $1 million in technology companies, among them ObjectVideo Inc., which specializes in video surveillance technology for vulnerable facilities such as airports and nuclear energy plants.

The magazine reports that the fund is almost fully invested, so May plans to launch Dinner Club IV soon.
