WOW.. Let's see here..
1. If a person is severely arthritic in their hands it would be easier for them to leave a sticker or stamp.
2.Leaving your initials would not be good as there could be many initials the same.
3.There is a reason people put in Bring Your Own Writing Utensil.
4. Finding a micro and not wanting to pull it out, sign it and then roll it up again as tight as I found it, in the rain is o.k. with me. I have found many micros like that and just put it back without signing. I am not going to log it in on the puter as I think this is a form of cheating. I am just satisfied and happy in knowing I found it... It is not all about the numbers for me.. It is the challenge.
Cache on and have fun fun fun
