I try to leave every cache the best I can so it's in the best condition for the next visitor. When I started Geocaching frequently, I put together a CamelBak Geocaching pack that I keep stocked with replacement logs of all sizes, plenty of replacement bags of all sizes, pens, camo duct tape, superglue, electrical tape,and a Leatherman. I never take the original log as this is the ONLY physical record of finders. I leave a brand new log in a brand new bag so the new log stays dry. I personally think this is best practice!
