Windfinder app seems to be pushing the stronger winds on Friday towards dusk. If it keeps pushing them later, then Friday may end up being a gem.
I think you are likely good with a minnow or waxworm under a float. Roostertails work well to vary up the color options, but if kids are small, not really going to work for them. Same with the trout magnets or other jigs under a float. Even a crawler chunk or smaller worm under a float will drive them nuts some days. Really depends if they are actively biting or not. Minnows are a great choice for small kids, but may end up wanting to take some home as pets... We have had many fatheads as pets as well as a stickleback that was in with our fatheads (lived close to a year in a 10 gallon aquarium). I used to fish NP when my kids were little. Great lake to fish for 1/2 hour, then run over to the playground, then take a walk or bike ride, then toss a ball or frisbee around.
It takes 15-20 minutes more from the Shaler exit to get to Arthur than it does to get to NP Lake. Less if McNight Rd is backed up, which it often is. I find it to be worth the extra time to hit Arthur. NP is a nice place to take a kayak for a ride and grab dinner and a beverage at the OTB. MUCH more eye candy at NP Lake than Arthur too. But also a lot more crowded in general.
