Easy way to get mowing them down Achievement
I dont know if this works in private free roam but it does work in public free roam. Go to the fort in mexico with the cannons and gattling guns. You will need at least three people to help you get this and you will also be able to acomplish several challenges as well and you should also be able to pick up most wanted achievement. there is 2 gates into the fort, one has a gatling gun that can rain bullets all over it and the other two has two cannons overlooking it. We did it this morning with 5 of us and it took about an hour and a half to get the achievement. The best way is to stay in open chat with everyone so if people come around you you can let them know you are nmot trying to kill them just the cops trying to get you.
Sorry to The Chief who got caught in the crossfire this morning. Hope you read this and thanks to CL0CKWORKORANGE for the help on this
Back in Seattle!
