I'm compelled to agree with you on this, Twist. I've seen bigfoots twice. Existence isn't in doubt for me. I've personally seen zero evidence of an organized coverup. I've seen people who just don't want to deal with the question on a personal level, but coverup? Nope. We have no tangible evidence for such a coverup, only a hopeful deduction one "must" exist to explain-away an inconvenient lack of evidence or acceptance. The simpler answer is bigfoot is not just blurry, they're stealthy as well.
Rumors of a coverup, rumors of gov't interference, etc are likely much more effective than an actual coverup with gov't interference could ever be.
