Where can I launch a model rocket from in Baltimore?|161553

I_ve been at Johns Hopkins for the summer and a friend of mine suggested that we build a model rocket. I now have the rocket but don_t know where to launch it. Does anyone know of any parks in Baltimore(particularly those close to the Johns Hopkins Homewood campus) where model rockets can be launched from?

Druid hill Park
Patterson Park
All of the high school_s in the area_s have football fields
