Yes, that's it ...although I haven't made any for a few years. It's a Porta-Trax, made from Ozite racing carpet ... the whole thing rolls up and fits under your arm. These should be much cheaper for me to ship into the US than the Mini-Z tracks; which I sold primarily in Canada because of high ship costs.
I just wish the market were larger to make manufacturing the track kits more than just a sideline ..let's hope the dNano takes off; although without a $99 price point I'm skeptical of the eventual market size.
And yes, it's not to be confused with the above poster's product, which looks completely different. - Lorne
