Santana tickets? At Ravinia, you'll have to wait

Tickets for this summer's Ravinia Festival concert series went on sale today, and word is that all did not go smoothly. 

Customers complained about spending hours on the park's flooded website trying to complete transactions, says CBS-2.  

“What an absolute train wreck of an experience,” one man wrote. “I was able to confirm purchase of Santana tickets but the site crapped out as I was buying other tickets," one customer wrote on Facebook.

This year's schedule includes Earth, Wind & Fire, Sarah McLachlan and Jimmy Cliff.
