…definitely use it! It’s a great parking lot for slow-speed practice, though the crappy quality of the pavement (lots of holes/deep cracks/really uneven seams) and its small-ish size start becoming a problem for faster, more complex drills.
As mentioned, however, it’s great because it used to be used for MSF classes and has all the lines painted on it. In fact, its such a staple of my practice routine that its featured in a few upcoming videos. Definitely check it out if you live in the area.
