Great recovery, good for you for sticking with it.
It reminds me of the first deer my freind shot when we were 15 yrs old, 20 yrs ago. It too was a rainy evening, and he shot a doe in a field of goldenrod at dusk. He was so sure he hit it, that we kept up looking for it for several hours with no blood, arrow, nothing!. Several hours later, following deer trails with lights, in the general direction she ran, we found a cupped yellow aspen leaf full of red tinted water. 20 yds later we recovered his deer, high double lung - 150 yd death run. Looking back, I still cannot beleive we ever found the "blood" before the deer.
Thanks for invoking the memory - Glad you recovered her.
