Can the classic 'Snake Bite' of a pinch flat be patched? I swear I read somewhere that It can't, but that seems silly. Also, DRietz, postage to Northern California from Michigan would be silly for old Schrader tubes, but I got 2 Presta in there too. I'm leaning toward the batch patch session, scuff up a bunch, put on the glue and work while it sets up. clamp the tube and patch between some scrap wood with a C-clamp so I don't have to hold it forever... wonder if that would work.
