yes it's very, very addictive, i only started finding cache's 2 days ago... already got other friends interested.
i myself drive a van around wigan/warrington/liverpool and today i found myself parked up at the side of a flash thinking... hmm i bet theres a cache here, 20 minutes later i've started my phone app up, found a cache a whole 250 metres from where i parked & i'm standing in muddy puddles in work uniform looking in tree stumps for my second cache find haha....
