Before you go

Check Conditions, Not Just Location

Location is only half the decision. Moon phase, atmospheric transparency, and cloud cover on the specific night determine whether the drive is worth it. A Bortle 2 location on a full moon night is worse than a Bortle 4 location on a new moon with excellent transparency. Check StarCast for your target location before leaving — not just the general weather forecast.
