What's the Opposite of "Sunbathing" ?

My guess is that it might be lying face down on mud in the pouring rainwhilst lowering a salinity meter down an open manhole into a sewer.Whilst I was doing the above it also occurred to me that I was coveringthe Rev. Dave's area whilst he was on holiday. It's quite likely that hewas lying face down on a beach in Tenerife in the blazing sun at thetime.
