We’re deciding whether to go to Magic Mountain on Sunday, September 20th or Wednesday, September 23rd, to avoid the long lines and crowds. Upon checking the Magic Mountain Crowd Calendar it shows Sunday, September 20th as “Hey, It’s Alright”. But we were surprised to see for Wednesday, September 23rd as “Yup, It’s Packed”. What is happening on September 23rd at Magic Mountain for it to be packed on a weekday in September? Could it be that September 23rd is Yom Kippur and the First Day of Fall?
