A shaddy $100 max cardroom (How can i beat it)

[lef1000]

I play at this place called the Knights of Colmbus, which hosts a bunch of 1/2NL games that are usualy full. The max buy in is $100 minimum is $60. They charge $2 every half hour. most play very loose and make huge pre flop bets ($15) with medicore holdings and bet regardless of pot size, others are very tight and passive. The worse of the aggressive players will play any two cards and even raise on them OOP and regardless of # of pepole in. Should i be call/re raising PF and on the flop or shopuld i just be check calling all the way down or bet'/ push???? For some reason i am having more problems with this then 1/2 where eveyrone buys in for $300 and its not as crazy.
