STF was started out in the suburbs of the 586 area in Michigan. Then grew and scattered around the 248 and 810 area. This group of friends all consist of the real straight edge lifestyle. they are always there for each other, no matter what, they have have each others backs. they beat you down for smoking or drinking. they don't provoke anything unless you'll give us a reason to. Each of them have our own beliefs, some believe in God, some claim to be God free. they are all about respect, and this is why they all get along, They are always going to be there for one another, forever.
