Museum of Science and Industry

My daughter and I arrived to museum today for September Sunday free. I was charged 22$ parking I read the parking fee i assume members or families where given discount or free parkin. I discovered that i paid 22$ for a free day. I believe that there should be a discount parking for non members and their families. If are a member parking is free. For Illinois residences their should be discount rate during stay of 2 or more hours. I dont think nonmembers should be penalized for wanting to enjoy themselves at the museum during September Free Sundays.I am a longtime patron im65 yrs old i grew up going to museum with my fsmily and friends. My daughter grew up going to the museum shes 42 yrs Im so disappointed i dont plan to return.
