Here in the northern regions of the US we will start getting our first frost of the Fall season.  Still waiting for ours here in Southeast Michigan, but it will get here.

When I see the weather man/women reporting frost for my area, I make sure to have my gear ready to go for daybreak.

At this time of year, the weather will warm up and melt the morning frost so you have to get out at daybreak as you will have limited time before it melts.

Frost adds character to any subjects making for great images.
