Hi, we are just getting started hiding our first geocache. So far, all the ones we've found have logs that just have space for the username and date - and that seems to be the only requirment. But is it okay toa also leave a space for "comments" too, in the log booklet we plan to use?I know my kids will get a kick of reading comments when we check on it from time to time - but I wanted to be sure it's okay to do.
