Then you guys need to drop in at J&M Hobbies in San Carlos, CA in the San Francisco area. The real deal, old-time LHS where you definitely would get your canopy, in stock, on the shelf, as well as all grades of real silkspan, Jap tissue, contest grade balsa, dope from three manufacturers, GLUE, props, Ultracote, Monokote, and several other kinds of 'cote, and all the rest of the stuff that makes our hearts go pitter-patter. Ted Fancher's "Intimidation" or maybe "Excitation" hanging from the ceiling (Ted lives nearby). Brodak and Sig CL kits and ARFs. They have to have the RTF electric stuff to survive, but they have all the things we need. I manage to get in there every few months ($20 in gas and a $5 bridge toll away) to pick up my necessaries. Shop is like a time warp, in an Art Deco building shaped like a ship, owned by the same family for at least 50 years. I am sure some of their stock is from the 1950s, like a museum. But all the current things as well. And guys behind the counter who know modeling and will talk modeling endlessly. Another good reason to live here.
