Yep, I did. It's been awhile since I worked with Peco Electro frogs and I merrily laid all my track and expected things to run. I forgot about gapping the frog rails or using insulated joiners. Right now I'm just using DC for testing but I still had shorts when certain turnouts got in certain routes. And of course the gaps will be important for DCC. So I took a break from adding feeders and started cutting gaps. Thank heavens for my moto-tool.  Found out something too, a small piece of Atlas N scale plastic tie works great as a filler in the gap.  I was trying to figure out what to use and looked down and there was a small scrap of N scale track on my worktable.
