Excellent article and good advice!

One piece of advice I would give everyone is to carry surveyors FLAGGING! You know, they sell rolls of the stuff in most hardware stores for next to nothing. We've used this for years to identifyshot locations and bloodtrail then kill locations. Tie a2 foot piece to a tree close to where ever you find blood. You don't have to worry about blood being lost due to rain etc and you can follow the flagging trail visually for a long way.

We also use it for flagging our way from the kill site to trailhead for multiple trips packing meat in rugged dense country.
