This cache is placed on a bit of no man's land that the city has for sewer access. They were nice enough to put a little fence between it and the homes so it doesn't look like the residents have underground missile silos in their backyard. No fences or gates are present on the public side, though, it is just a wide spot off of the sidewalk.
Parking is allowed on the street, one should be able to get very close.
Avoid Muggles.
The cache is log only, bring your own writin' stick. Please replace cache as found.
