Pretty simple cache if you know what to look for. There's a decent amount of traffic in the area at times but it's usually not too bad, and it's also located near a neighborhood so be mindful of muggles.
It camouflages well, so as long as nobody sees you grab it and put it back, then you should be fine.
Congratulations to Goldenhawk for FTF!! (sorry for the mental anguish)
