I'm taking my kid to the Nationals-Giants game on Thursday. Anybody charged nearby? It's a late day game, should be done by 8pm. Plugshare shows some nearby chargers but I'm not clear on availability after normal hours or feasibility of parking during a ball game. I'm staying with a friend in Potomac that night and can charge on his dryer outlet but total mileage to game and then his house will be about 215 so I'd like to have some backup charging if needed. I'm trying to avoid the 2 hour round trip that a Metro ride from Rockville would entail. Thanks in advance!
