Subject: Re: GPS and geocaching
Hi Ziners, I know this a site for Ziners to trade travel information, but for those of us who are technical neophytes, can someone please explain the usefullness of a GPS. And what is geocaching?

Diane wrote about viewing the Coloseum and the Vatican and I'm wondering if this is a virtual tour before and/or while you are there. I'm a carry-on traveller (if I can't buy it, I don't need it) and don't even bother with a camera or hairdryer, so wonder how much added weight this would be and more important, am I missing something? I'm still relying on the Michelin maps to get me to places. I don't think I've missed much on my world travels, but who knows? Lucy, Toronto
