They call these roads, or this location.. Giomarra.. Maybe thats the name of the housing area its located in (rich ass mother ****ers) But It's in glendora and these roads are kick ass! Take the 210 and exit auto center, its near foothill.. The roads are closed at night though so go during the day and lay low.. I went with my friends at 1 am.. THere were me and 2 of my friends with wrx's... Looked really suspicious, 3 wrx's driving in line towards the same place.. COps saw us and right when we got the CLOSED gate into Giomarra, an SUV truck police car comes up and tells us to leave .. Oh well, good luck finding it, kinda confusing to get there once i get iron clad directions I'll post again.. Anyone heard of this spot?? It's really popular..
