RBC Brooklyn Half - May 16

Hello,
I’m running the RBC Brooklyn half this Saturday and I am planning to drive up from Philly the morning of the race. The plan is to park my car in a garage near Prospect Park. Based on the road closure list I should look for a garage on the West side of the park. Anyone that’s familiar with the area and can recommend a garage? Does anyone have any experience with a situation like this? Thank you all!
