@HoughtonLikeTheLake - Oh my gosh! You have me in a fit of laughter. That first photo with his hands showing the spider's size is hilarious!
I have been on your friend's side of this scene a few times too. A snake falling into my canoe in Louisiana led to maybe the loudest shriek of my life!
Have you had any too-close-for-comfort moments of your own while paddling around?
