The Opposition Memorial is a graveyard in Hashbury, San Fierro, near the Hippy Shopper. The graveyard consists of three terraces with 72 graves in total. Plaques with honored names are attached to the walls opposite graves of the two lower plateaus, although they are poorly textured to be read clearly in the game. The memorials' first looks appear to be a graveyard for war casualties, but if inspected closely, the phrase RIP Opposition 1997 - 2004 can be seen on each and every gravestone.
Rockstar included this location as an Easter egg to make clear that competing games like Driver and True Crime do not stand a chance. The birth and death years of "Opposition" refer to the release of Grand Theft Auto in 1997 and GTA San Andreas in 2004.
