This isn't an important issue, but thinking about our adventures is a kick.
Last fall we were out 'scouting' (being pretty lax about it) prior to moose season. We parked the truck at a lake- it looks like 2 lakes with a round brushy peninsula type thing between them. My dh and young 'uns went to wet a line & see if anything was biting- I went to get rid of some coffee. I walked around the peninsula thing- there was wheeler trail or something, but it was super muddy- so I skirted it & walked in the grass along the trees & brush. Man, it was gorgeous & sunny out. What could go wrong? I kept looking back & went round until I couldn't see the truck. I unbuttoned & went to position myself & I heard it. I have never heard the noise before. It was a very low - not really a growl, kind of a vibrating type sound. Sounded like it was being broadcast out of a barrel. Sounded big & deep & got my attention. There was no sound of brush moving. Well, I didn't look around- I pulled up, buttoned & got the heck out of there in very few movements. I never saw it! Initially I thought bear- dh thinks it was a moose (we saw plenty in the area).
I thought it was strange, but if the critter stepped into the brush as we approached- he would have had no way to leave without walking into the open & the peninsula wasn't that large. I was shocked that I heard NO movement- just the noise.
What do ya think it was?
