Mars Trail Over Evolution Lake

My first attempt at a star trail, taken on August 27th when Mars was closest to Earth. I left the shutter open until 4 a.m. and then woke up to shut if off, but by then the lens had fogged over so it didn't capture the whole trail. I was wondering how it was gonna come out. Oh well. I'm also surprised at how light the sky is in the photo, I didn't release the shutter until it was nearly dark. I've got a lot to learn with these star trail things!
