Just want to start off by saying that nobody should apologize for "hijacking" this thread, as long as there is some constructive conversation going on! Part of the reason I wanted to create this series was to get people talking about canoe camping, and if people can draw ideas from what they've seen and expand their knowledge by discussing those ideas with fellow campers, I'm all for it!
So to join in on the conversation....
SPAM (what IS that stuff?).... Notice that during my quick appearance at the end of the episode, I was not consuming the pink mystery meat. Having never actually tried it (and not really wanting to), I don't believe any condiment could save that little pink brick. Markus was kind enough to send me home with a "SPAM single" to try on my next camping trip.
In regards to the tarp over the fire, there are a few points to consider:
1. What is your tarp made of? A silnylon tarp for example, has better heat resistance than most other lightweight synthetic materials (ex. polyester, urethane coated nylon). *Key word is RESISTANCE, nothing is fire-proof*
2. Hanging arrangement. As others have eluded to, hanging configuration can make a huge difference in terms of keeping you and the fire dry, as well as how heat/smoke are trapped (and thus burn risk). This can obviously depend on things like the size of your tarp, available guy-out points/trees. Keys are to keep it well above the fire and embers and allow room for (at least some) heat to escape.
