Spring Break, Long Exposures and Law Enforcement

So this week about all the photos i have taken have been long exposure shots. I find them to be very artistic and something not seen very often. I uploaded my first one here earlier in the week.

On Wednesday night i got this photo at the Prairie street bridge going over I-35.
In this photo you see the north bound traffic with their head lights and the south bound red tail lights. As a side note after getting this shot i headed to the graphic arts bridge and got up on the sidewalk then had the first police officer stop turn his bright lights on and talk to me.

Then on Thursday night we had a spring lightning storm roll through our area.

On Friday night Madeline and i were in Wichita and on the way home i stopped to grab this photo of the spring burns in the Flint Hills as cars blow right by them.
While getting this photo on the turnpike i had a trooper stop pull over and turn his bright lights on and question me about what i was doing and once again had no problem and left. So a note to anyone else is be ready to talk to law enforcement if you are shooting long exposures at night.
