This is a very high traffic area, many Muggles. Use extreme stealth and the cache is yours. The blue pill has been removed so the title has no relevance to the cache now. BYOP Props to NonaMirjana and JunkMan024 on the FTF!
I can't believe I have to say this but when logging your find DO NOT add pictures and descriptions of the exact cache location. I have had to delete a good amount of logs recently because of this
