I can't count how many times TESKELLY has replaced broken caches, or how many times we have replaced swag in caches due to it being rusted or all wet, or even the log books.
If we don't have a rag, I just use my shirt....lol
We usually carry around baggies and extra log books with us...not really cache containers, but if the van is near, ya never know, it could be one of those days.
I agree, though. It is great to be able to help out the CO and save them the trip of having to rush out to the cache to put in a new log book, or swag, or a baggie/pencil. Those are not heavy items to carry on your person, so really it isn't too much to ask a cacher.
It is something that should be added to taking part in the sport I believe.
