Today we present a sequel to the entry of March 14th, from a deeper stratum within the same jumbled box. These are probably from the same week, if not the same day.
Here we see another view of Evel's Snake River Canyon jump on 9/8/74. Again, it's not particularly accurate in depicting the Sky Cycle, but I did correctly portray his failure to make it across.
I don't know what he's jumping over here, but I think that it's a shark tank (does that look like a fishtail coming out of the water to you?). He did attempt (and fail) to jump over a shark tank in the winter of '76, but I don't think these drawings are from that late.
