"i do not wish to see any otters harmed in your flying adventures"
First, thinking to myself, "wow, that Parker is using otter fat in his homebrew fuel...he is hardcore. Although, on another forum Jan of Viking noted that 100LL & Decalin doesn't work for his engines and now recommends Marvel Mystery Oil. The NTSB says the mystery in Marvel Mystery Oil is lard. So not too far off!" No, I knew what you meant.
