rush

which ever one you like best

KSIG, SAE, DU, Theta Chi, Sig Chi, FIJI, AEPi are top choices and all have a good time after that don't really know too much not hating just really don't know also definitely do not just follow greekrank rankings TKE is not even close to being a top house

Depends on what you're looking for. If you're looking for the true "frat bro" experience look at sae, sig chi, du, ksig. If you're looking more for a nice balance of social events and brotherhood look at Theta Chi, Fiji, Delt, Aepi, pike, zbt. If you're looking for a more relaxed frat look at tke, beta, lodge, sammy.

Your best bet is SAE, DU and KSig. Maybe even Theta Chi or Fiji.
SAE and KSig had massive pledge classes so I dont know how prominent they are on getting spring pledge classes so try out the other three. First three are your best bet though.

Just rush a lot of houses and find the one that fits best honestly, all houses have a vibe and find the one that fits yours.
