I came because it's Christmas, it's for charity and mainly for the nieces and nephews.
We piled as many as would fit into my brother in law's truck bed and did the slow lap around the speedway checking out what local businesses erected as their show of support for the cause.
Set your stereo to the assigned station and you can listen or sing along to the Christmas tunes as you check out the displays.
Military discount (active duty or retired) as both my sister and her husband are in the Air Force. Not sure what the full cost is; you pay per vehicle and our cost was $13.
