I shot a spike this morning not long after sun up, and thought I hit it pretty good. But when it ran off, it didn't run like there was anything wrong like they usually do. I gave it a half hour or so and then started out, found my arrow covered in blood, no green stuff but no frothy bubbles either. I started up the track and jumped one about 100 yards out, but it just walked away instead of running. At this point, I went back to my stand for another half hour and waited on my dad to help track. We found a lot of blood, then lost the trail. Found more about a couple hundred yards down the trail, then nothing again. I finally gave up after about an hour from the last time we found anything. Dad says I didn't hit anything vital and it's going to go find cover and heal up. I do think that I hit it low, I aimed on the 30 yard pin and it was further back in the opening than I thought. First time I've ever lost one.
