text: seriousilly, i'd map from an arse perspective.  and i can't recall a bench near me that was anything other than wood - no plastics.
  
  well, there may be stones/concrete making an impromptu bench, but that would be sorta like tagging the stairwell to my flat where i sit for a spell whilst removing me shoes distracted by trying to finish a beer, something which i have not mastered simultaneously.
  
  as far as the supports determining the profile of the typical arse position when upright, or whole body position when not, there are three possibilities near me.
  
  one is where a steel frame surrounds the arse supports in a flat but angled position which is perhaps ideal for sleeping.  the town over that way seems to use those.
  
  then you have either a concave or convex sleeping surface, which also determines danger to beer, as one of the four slats will be optimal for beer cans, but if it is a concave arrangement, i feel my beer is safer from being clumsily knocked over by my incompetence as i can perhaps rescue it before it empties itself.
  
  now i hear you asking, why not a bottle, as those can be almost re-sealed with the Kronkorken if carefully removed as i do (ask me to show you my collection of bottle caps.  or better, don't.)
  
  well, as a race to the bottom, i've been getting the cheapest beer available, and it comes in a can.  comes in a can.  it comes in a can.  and it is depressing that g00gle cannot point me at the particular cultural reference i quote from probably half a century ago.  i despair for our youf.
  
  anyway, all that is rubbish as the point of this post is to reel that thing back in and post a frank zappa song, as most likely this thing will be unplugged before the end of the week and not re-plugged after battery operation, so *ZZZZIPP*

  i had to throw that out there to compensate for my inadequacy in the rest of me miserable life.
  
  i believe i am now at maximum comment length.  qx
