Cruizin With RC’s is in Waldwick, NJ and they run Mini Z’s in the shop. They also have an outdoor turf track used in the summer.

1/10 definitely has many more options for racing than Mini Z. But, you can do what I did, which is get a RCP track like the Mini96 for home. This is usually the same type of track used at most other tracks although smaller sized tiles. Great for practice at home if you can’t make it to a hobby shop’s track regularly.
