ok first you need to find one by the freeway...at least within 6 blocks or so....a fast car, preferrably one that is common on the streets, no flashy colors, or have a second car waiting....i'd recommned fully automatic weapons for the job,
a few weeks before scout out the bank your thinking of, check to see the number of cameras, the postions, number of tellers, aveage amout of foot traffic duirng closing,location of the vault....etc
wait....your talking about USING a bank...to like....keep money in right?
never mind
