I'm planning a trip this auguest for the oregon coast. I live in northern fricken alberta and its gonna be a long one. I've never taken a trip this long and was hoping to hear from the touring guys as to what kind of supplies I will need to take. I have a chase vehicle for most of the trip to carry things. I'm thinking a set of tires, a chain, some sprokets, oil, oil filter, and some bulbs and fuses just to be safe. Am I missing anything I should have with me for a "just in case" measure?
