I'm a newbie.  I live ~4.9 miles from a class B airport.  I have a park about 1 block, <1000 m from my home.  I would like to use my new P4P to get some winter shots of the 40" of snow we have on the ground.  I'd only be flying at 50-75' for 10 minutes or less.  When I check B4U Fly, it says I can't and AirMap says I need authorization.  I thought there was someway of obtaining online authorization to do a limited flight within that airspace.  Any help appreciated.
Thanks!
