Grad adventure in May is for middle school students
Their tickets will allow them into the parks as early as 4:00 pm
Park closes down to the public for this event
Don't remember if it is at 5 or 6 on the Friday nights in May
Only 3 Friday nights are included this year for it
The UO website should reflect the park closing time for those without the grad adventure tickets
Or you can email or call first services for more info
I have been a teacher for many years
i don't attend them but the kids do love the special events
