1.  Toilet seat covers.  In California all bathrooms are required to have toilet seat covers.  Multiple times I have walked into public restrooms and do a 360 degree turn looking for the dispenser only it is not there.  Honestly this is not a big deal to me, but I am just so used to using these nice little paper sheets.  
2.  Conservative talk radio.  I was driving along listening to 1350 KMAN out of Manhattan and the radio personality made a joke about Al Gore.  It took me by surprise.  Al Gore is so respected on the west coast.  
3.  Kansas apparel.  Occasional on the west coast I see KU or K-State gear, and I always have to do a double take.  While in Manhattan I saw plenty of people wearing K-State shirt and I always got a little excited that I have something in common with these people until I realized where I was.
4.  Seeing forever.  As I was driving to Buhler late one night and saw a flashing red light warning there is a stop sign.  I turned off my cruise in preparation to stop.  6 1/2 miles later I made it to the intersection.
