yes the twin cities (minneapolis and surrounding areas) have a lightrail system--and people have hit it up (ran once, buffed, never went back up)
The problem is, you cant do any fast action shit--nor can you easily access the lines.
Theres rumors where the lightrail yard even is--some say its down by the old central station for the state (closed i believe)--others say its in the burbs--others say its in minneapolis--The ones whove seen where it is dont tell--but all that's been said is that its pretty fucking hard even getting in to see the trains themselves.
You cant action hit the bitches since they go so fast (if you tried hanging on, your ass would fall off for sure, those bitches dont stop for anything)--plus the stations are so hyped for safety that getting your cans on or a marker would be seen (and your ass would get arrested)
Us MN writers stick to walls and freights--but It HAS been hit all the same
