714 Algoa Friendswood Road
(my maps below are better than MapQuest!!)

Coming from the west or northwest Houston:
From Alvin go about 4 miles east on hwy 6 to just before the flashing yellow light (for Mustang Road) and turn left onto Algoa Friendswood Road. FDO is about 1/4 mile on right.

Coming from the east or northeast Houston:
My preference is to take fm 517 (Dickinson exit, #19) from I 45 south. About 5 miles west of I 45 is the Wild Animal Park, and you turn left at the next street, Algoa Friendswood Road. After about a mile is a stop sign, continue on another 1/2 mile to FDO on the left.

From either direction there is a bright orange Paintball sign marking the turn onto Algoa Friendswood Road.
