Why does it cost me $12 to see my own city?

SO! Today we (my mom vik amber and myself) went to lunch with two of my mom's really good friends, Lily and Esther. I LOVE MY MOMS FRIENDS. Lily can make me laugh for days on end, I absolutely adore that lady! Lunch was great too, can't beat that mexican cafeteria food! Anywho. After that we went to Jamba and cute boy started dying over Amber again. I got my last Acai of the trip (:[ ) and we walked ove rto the Sears Tower. So okay, here's my question: WHY DOES THIS ELEVATOR RIDE COST SO MUCH? Really, I just do not understand. I won' lie though, it was a sweet view, and I learned some cool facts...but I don't know about $10+ worth. Anywho. After that we walked down to Garret's, got a mixed bag and then went to the Target on Clark and Roosevelt. (which I absolutely love) I miss those cart escalators! After some wandering in there we headed home, which brings me to the end of today! Time to start packing soon...this trip ends in 3 days...
