OK boys, I took delivery of my ParkSmart CleanPark Mat. Made in the USA (Cali) and purchased from Edmondton. They have a 16', 18' and 20' model, all 7 feet wide. I bought the "regular" thickness 16' mat for $179, plys $33 shipping (FedEx to your door). They also have a "HeavyDuty" mat with Vinyl that is twice the thickness, which are also twice as much coin. Since both had the same 1 year warranty I didn't bite. It's a great idea in that you just unfold the vinyl sheet and snap a "curb" all around, which retains the water/snow/slush/etc.
After thoroughly cleaning the floor it was easy-peasy-lemon-squeezy. Took 30 minutes. I'll be re-vamping this 2-car-attached to make it all purty (including putting down epoxy) this spring, so this was a must.
