This is developing into a hobby which sits nicely alongside my other activities, such as running, walking and even visiting other locations whilst on business or vacation.
Basically, Geocaching is Hide and Seek for the 21st Century. People hide things and you have to find them.
There is also a touch of the cloak-and-dagger, dead-letter boxes and of waiting until the coast is clear.
The 21st Century element comes from the integral use of the internet, GPS technology and – generally – mobile devices.

• Scene: 1pm, a busy shopping street. A statue of a local poet faces me as I sit on a sturdy iron bench. Yes, this looks like the spot. With my right hand I reach under the bench and retrieve a small film canister, held in place with a magnet. Inside is a roll of paper listing the previous finders. I add my details and return everything. All that remains is to log the find on my iPhone App and the job is done.

The leading organisation for this hobby is Geocaching.com. The easy site soon draws you in and apps are are available for most devices. I’ve tried both the iPhone and Windows phone versions: the former is superb, whilst the latter needs work.
