Great free museum courtesy of USF! Though it's free to enter, the way they get ya is that you still have to pay for parking (during the week)... and that's if you can even find it during peak hours!
The museum hours are slim, especially on the weekend when people actually have time off of work, so make sure to double-check before you go. On Saturdays they are only open 1-4pm, and forget coming on Sunday because they aren't open then.
USF does a great job of rotating a lot of interesting and relevant exhibitions, including those of their MFA students for their thesis shows. Besides the shows, they provide a lot of artist talks, guided tours of the CAM, receptions, and other interesting programs that are usually free and open to the public. What a great way to make art accessible to everyone! I recommend finding them on Facebook so you know what events are coming up in the future to mark on your calendar.
Best time to come: reception nights! Besides being in the bustle of campus life, they usually provide small bites and a fun atmosphere for viewing the artwork (plus, free parking after-hours!)
