Bee,

What is great about Rite-in-the-Rain paper and a Fisher Space Pen is that you can have the paper underwater and it will still write a clear line with no smearing. If you use a pencil the message could be very faint and hard to read. The pencil marks could smear and become impossible to read if it gets wet.

Dear rescuer,

I have gone NE to the small pond in the distance. You can find me there.

Thanks!

If the "NE" and "pond" are a smear the note will not be helpful.
