Typical boring KK hand

[GoCubsGo]

Villain is 30/10. Earler he reraised all in with JJ preflop, so I really doubt he has jacks, queens, or aces.

I don't really see any other line I could have taken with this, yet after he called the turn, I had this sinking feeling that I was up against a set. Is this a standard play at NL100 or do I need to slow down? Are there still enough bad players at this level that I can expect to be called by a flush draw, straight draw, or TP type hand?
