Illinois Senate District 8 actually doesn't look all that weird: http://www.elections.il.gov/Downloads/VotingInformation/PDF/2011Districts/2011SenDist8.pdf http://www.elections.il.gov/Downloads/VotingInformation/PDF/... At least it doesn't in comparison to the Congressional districts like, say District 4: http://www.elections.il.gov/Downloads/VotingInformation/PDF/2011Districts/2011CongDist4.pdf http://www.elections.il.gov/Downloads/VotingInformation/PDF/... That narrow bit on the far west is just I-294. No residences.
