I noticed after playing gta4 for a while that there were really no offroad races in multiplayer. Soooo, me and some friends started making up our own races a while back (like the new game to the sultan rs and back etc) This one is pretty cool, and its probably one of the coolest off road areas on the map (although there is more coming soon... lol) This is an awesome race in multiplayer and you can do it and get a respawn if you choose the map right next to there (i think its called driving while high) and theres a check point right there at the gate. (convenient?) So it works out pretty cool and keeps people from crying too hard about crashing into the ocean because you can respawn right there at the begining.
Anyhow, give it a try sometime! I just used the noose patriot because it always bounces around kinda crazy ont he road I figured it would be decent on the rocks and shit. (this time is totally beatable lol, i lost it a couple times)
