Wasting a trout stamp

[MoLip]

I'm a new member to the forum, but I've been reading it for the past 6 months. This is the first year that I bought a trout stamp and I haven't had so much as a nibble so far this year.

I've tried Duke Island Park, some smallish pond in Milltown, Assunpink Lake from the shore, and by the bridge in North Branch so far. I was going to try the South Branch next, but haven't settled on a spot just yet.

I've been using powerbait, salmon eggs, and spinners. I have a light spinning rod with 6lb red colored mono line.

Any tips you can provide is appreciated.
