Hello everybody, please allow one question slightly off topic from gemany: Where to buy Inkjet-Papers in or around San Francisco? I'll be there in Spetember 2010 and like to fill my luggage with some inkjet-papers (especially those without OBA's), and, if possible, with some Itoya-portfolio-maps. We don't have many of theses items here in germany. For this, i'm searching one or two shops in the San Francisco Bay Area where i can get all this together. In this case, google hasn't been my friend, so i hope for your help. I'm looking especially for papers mentioned by Paul Roark and/or Clayton Jones. Best - Thilo
