I've wandered around several "Canadian Tire" stores, so if you've got one, there's at least some things there that can be used. Epoxy, screws, silicon gasket maker, aluminum, paints, thinners, batteries, wire, naptha, Coleman lantern fuel, lawn chairs.
The 28ga. wire is a bit tough to get here, actually. Craft shops might have it, but it might not be copper, and it does need to be copper. Tom Morris, Jim Lee, Randy Smith, RSM, Brodak, and the rest of the vendors below in the Vendor's Forums are about it. As long as you've got postal, UPS, FedEx, and a computer connection, that's about as good as many of us have.
Fuel is the one thing that most of us rely on a hobby shop for. We make a "fuel run" to a source, and a few get a case or pallet of cases shipped in by truck...not cheap. Those of us who have access to fuel, try to take care of those who do not...we bring it to contests, some guys will bring it back from VSC (Tucson, AZ), etc. Fuel is the tricky part. If you find a friendly hobby dealer, they'll usually order "good fuel", if you're willing to buy a whole case. That's often only 4 gallons...sometimes 6. Not really a huge amount.
There's apparently a fair group in Winnipeg (call Larry Maltman) and Edmonton, a few in Calgary, a few in Saskatoon, etc. If you want email addresses for those, most are probably members here, or send me a PM.
