There is an unofficial off-leash area there, where local dogs meet for daily playtime, between 5:30 and 7:30pm. Though it is not an official off-leash spot, I go there several times a week, and have never had a problem. It's a really nice green space: all grass, no dust, so you won't leave the park with a filthy beast.
There are already three or four Danes that are there on a fairly regular basis.
It should be noted that this area is not fenced in. So keep that in mind. The upside to that is that all the dogs that frequent the spot are well behaved, which makes for a pretty chill experience.
