Filbert St. is located between Arch and Market Sts. in center city Philadelphia. If you guys could only see what they are doing to the Dyottville Glassworks site right now. Its been dug wide open down to the original brick walkways, etc. Its down the street from house, and I wanna jump outta my skin every time I pass it! Lots o digging round here for highway work at the moment. AWESOME bottle by the way, I'm jealous, sorry for going off track, had to share that little tidbit. ---Joe
