Nice work Dave! I see you do quite a bit of Roof Cleaning up in Aurora, Illinois. I did not know that Aurora was in DuPage County.  I always thought it was in Cook County Illinois ?

DuPage

Dave, how far is DuPage County and Aurora from Chicago and Cook County ?  The reason I ask is I know they have big Fireworks Celebrations for the 4th of July up there, because I read some people actually watch them from their roofs. 

Cook is a large county and is adjacent to DuPage. Aurora is about 45 minutes from Chicago. We have big fireworks just about everywhere up hear. The Chicago gang bangers shoot off their guns and we shoot off our rockets...LOL.

Is Aurora and DuPage County built along Lake Michigan, like Chicago, or is it Inland ? We notice that homes built on freshwater lakes or ponds seem to have roofs that get dirty and require cleaning faster, thern homes built inland, and away from freshwater.

they are inland.

Wow Dave, I never realized that Aurora was the second most populated City in Illinois. According to this it is https://www.facebook.com/pages/Aurora-Illinois/103724136333224 and it is so big, it is in more counties besides just DuPage!
