A wild 30-60 limit holdem hand

After playing some 10-20 6 Max NL yesterday (this morning?, how do you call to the 3-5AM hours anyway), I decided to play some 30-60 limit, I like to play limit because of the action, and I like specially to play short handed, more action !!, but here we were playing 9-handed, that's why I consider it a little wild for my tastes, but maybe not, I'm not even sure if I should have bet the turn with all the action, but for sure the river bet was fine. Here is the hand:
