Kidding, Burton Park is open to all, the title will make sense when you find the cache.
Burton Park Square (GC4ZZB8), a cache at this very spot, was archived 5 years ago, and this area went cacheless for a few years. Triples Alley (GC7T2JD) was placed in 2018, but had to be archived recently and a new one by the same COs was placed nearby. But this corner still had nothing, so here I am with the sequel to Burton Park Square: Burton Park Cube.
If you found GC4ZZB8, look where you looked back then. If you didn't, check the hint.
