Good thinking about the PVC for the flag. Remember that the higher you make the flag the more tippy the whole thing will be. See how the the top surface is all scuffed? I had in mind painting it red but held off until testing it, so if it turns out good that would be a nice touch. I thought about the possibility of attaching ballast to the fin but it didn't need it.
Ever dream that while out there you'll shoot a 100lb king fish passing through by chance? In that dream that eye you made for the float line pulls out the two screws
Cool pooch. Is that a stuffed toy he got there or is he bringing you tools?
