Unfortunately, in December it will be dark most of the time. The OP doesn't say when in December, so let's just pick the 15th: sunrise 9:18 a.m., sunset 3:12 p.m. On the positive side, the Christmas lights should be in full bloom, which helps a lot. And if he's very lucky, there might even be a little snow on the ground, which also tends to brighten things up a bit.

cheers,

Henry
