T3 and t2 frats

Of the ones you listed, a true open rush in the spring done is really only done by Fiji and Sig Chi.

“Open” rush, where frats look to pick up a few kids that know their already selected bids well is done by every frat except Castle and and sometimes zete and hall. How many they take, and if they bother at all, is determined by how well their dirty rush has gone.

Off campuses groups do it a little differently. Some (like owls) are perfectly fine with getting 8 kids in a PC and therefore don’t bother with even the impression of open rush. Theos will never do it. Apes will do it if they’re scared of their kids being stolen.
