Is it viable to sarge a campus of a college you don't actually go to? Or is it too much of a closed group dynamic?

I think it's better to be honest. Sarging in a closed group dynamic that you're apart of often results in gossip and drama. Everyone knows you, and everyone knows who you've hooked up with. Girls usually don't hook up with guys that have been with their friends (I said usually). Thus, your chances are dramatically decreased off the bat.

If you're sarging where you don't know anybody, this is PERFECT. What do you have to lose? If you get rejected, who cares? You don't have to see them the next day. Most [single] girls are open to getting approached by unfamiliar men if they come with confidence and wit.
