Restonians flocked to Lake Anne Plaza on Saturday to help Reston founder Bob Simon celebrate his 101st birthday.

Simon has been feted at the annul Founders Day since he turned 90.

Local dignitaries such as Sen. Janet Howell, Del. Ken Plum, County Board of Supervisors Chair Sharon Bulova and Hunter Mill School Board rep Pat Hynes stopped by to wish Simon well, as well as take part in a “Cards Against Humanity”-style Reston game.

Simon’s birthday was on Friday. He kept a busy pace on Saturday, taking part in the Reston Little League Parade at Reston Town Center and helping kick of the Nature House Fund Run 5K earlier in the day.

Simon’s secret to being a hearty 101? A gin Bloody Mary and a martini daily, as well as lots of naps and walks, he says.
