How many miles will I drive....

Using up more of my accumulated vacation for the rest of this week. And I am going to be doing some driving between different photography outings.

The challenge is to guess how many miles I rack up between now and Saturday evening. Closest guess wins a 8x10 of print of my best shot of the week.

The only hint - I will only be going to one other (besides Arizona) state.

Any takers?
