It's a real dog park now!!!!
I went back to the Steele Park Dog Park after reading the more recent Yelp reviews and decided I should give this place a fifth chance...and I am glad that I did!
I am happy to report that there are two large grass area fenced off for big dogs and little dogs. This is also the hep place to be for Central Phoenix dog owners, as there were about 15 other pet parents present.
Good upgrade, City of Phoenix, now let's work on that mythical Downtown Dog Park!!
