I checked with LG today, and my 735 does not allow me to geocache :(
However, the handheld GPS that we will be buying for use on our cruiser will. Hub and I will be looking for that in the next few weeks.
In the meantime, I've signed up with geocaching.com and am awaiting an e-mail from another local gc-er to learn about any groups that meet/share stories in our area.
I can be patient!
