A rigid "plastic" sled like an otter or similar brand works better than anything I know of . I put eye bolts along the sides and tie the bear down with rope in the sled. If the sled turns over, the bear stays in the sled. They float if you cross water too. If you do alot of dragging, there is a cable winch unit that attaches to a chainsaw in place of the chain bar. It holds approx. 125 feet of cable. They cost around $800.00. It does not sound so expensive when you need it.
One of the most important pieces of equipment that you will take hunting is a good quality pair of optics and they take some care to give you the performance that you want. So here are a few tips.
Use some alcohol and cheese cloth to clean the lenses. I will usually pick up an extra cleaning kit from my optician when I have my eyes examined.
Don't touch the lens with your fingers. If there is a stick or a bug on them blow it off.
Use the lens covers. They are there...
