Call out threads are really dumb.
I live in boulder and I don't post a call out everytime i see a subaru or jeep cruise by on the hill with an NS sticker saying hey who was driving a subi at 330 on the hill in boulder!?!?
If you really wanna meet em go up to them and be like hey man i am on NS as well man whats your name dude? Hey maybe we should smoke a j and hit some urban sometime. Make a new friend. and if you don't see them the rest of the day does it really matter?
