Sparrow:

Go to the roof of the building where you first started G Spotlight and there
will be a Sparrow parked there.There is
also one on the roof of a house near the Pay N Spray in Ocean Beach. To get
to it, go to the Collars And Cuffs in Ocean Beach. Then, go down that alley
where Collars And Cuffs is and there will be a parking garage on your right.
Go to the top floor and there will be some ramps. Before jumping, look around
and find the Sparrow and then jump to it. I'm not sure if you can reach it in
one jump or not so you might half to jump more than 1 roof. The parking
garage is also located near the Pay N Spray. It is white and has around 5
stories. For the easiest way, just get to the Pay N Spray in Ocean Beach.
Now, go to that place right by it with the parked PCJ-600 and Banshee (or
sometimes Cheetah's or Infernus's). Now, get the PCJ-600 and back up all the
way from the white stairs. Back up until you have crossed the street and have
went in the alley with the gray pavement. Keep going back until you reach the
shrubs. Now, punch the gas and go fast and hit the stairs. You need to clear
the first building and land on the second one. It is pink. The Sparrow will
be up there. There is also one across from the Links View Apartment. Across
the street from it is a building with an arched entrance that you can go in.
Go inside the arch, there will be some backyards. There should be a Sparrow
in the first one on your right.
