Baltimore? Be careful - cold weather!!!
From personal experience, driving at 55 mph, full Range mode charge, and Range mode heating at sub-freezing temperatures the car is good for about 220 miles. You could try it at 50 mph with the heat off altogether (seat heater is okay) and you might make it. Bring a hand scraper in case the windows start to frost up!
Don't attempt the trip unless you can identify a charging location KNOWN TO WORK and have lots of time to wait for it.
Keep the energy app on the touchscreen and keep an eye on the Projected range (be sure to select Average). Use the GPS to get your distance remaining, and keep the Projected number higher than the distance! If it's going the wrong way then slow down, turn off everything but the seat heater, and if necessary stop to charge. Expect to charge for at least a couple of hours.
If you can do the above, then by all means go for it! I did a longer trip than that to bring my car home. But don't approach it casually.
