terminology question

i'm still a relatively newb cacher.
i keep stumbling across terminology that i can't find definitions for in any geocaching glossary or lexicon.

i saw today that a cache i had found previously is not listed as a "redman"
and noticed a lot of new caches in my area that are "redman" as well.
what's a "redman" cache? :?:

thanks for your time! 8^)

They are usually nano or lens case holder hidden on fire hydrant ..and Welcome to the game ... :)

I am still learning a lot of this stuff myself but this should be a red fire plug. Also yellow top, yellowman, etc. are fireplugs.
Good luck. If I can help in any way just holler.

Welcome to the world of geocaching.

thanks! i appreciate the response!
i'll know what to look out for now. :D

dont worry i didnt find anything the first three time that i went out
