Only six years old, Jane Milligan of Regina is a veteran of the high-tech hobby called geocaching.

That's the activity where participants hunt for hidden outdoor "caches" using a global positioning system (GPS) unit.

Milligan has been hunting for secret treasures this way, with the help of her parents, since she was two.

On a recent outing with her mother, she was focused on her task as she tromped through a park in Regina with her GPS unit in hand, but could barely contain her excitement as she zeroed in on her target.

"A little bit that way…

"I hope it's not right through a tree," she said, as she looked up and saw that the way appeared to be blocked.

But then, she reached a clearing and closed in.

"We're five metres away! Over there! It's right there!"

Sure enough, near some rocks she found a plastic container with some objects inside: an eraser, a nail file and a postage stamp among them. She helped herself and replaced what she took with some booty of her own: a handful of colourful bracelets.

Then she carefully put the container back where it had been cached and was on her way.

According to the website geocaching.com, there are hundreds of caches scattered around Saskatchewan.

Some of them contain "travel bugs" so people can track items that are taken from cache to cache.

Lori Milligan, Jane's mom, said her daughter has had a lot of fun keeping contact with other geocachers, who have developed their own lingo to describe the activity.

Non-geocachers who stumble upon caches have been dubbed "Muggles" — the term used in the Harry Potter books to describe people without magical powers.
