Snail Shell!

It's been raining all day, but at least the wind has dropped.  Did a bit of shopping   -  a girl's gotta eat!  -  and got home to find this snail on my door-step!  Brought him in to try some macro on.  I wanted to get the centre as sharp as possible  -  took lots of shots but that centre point was quite elusive when it cam to sharpness.  This is the best I could manage using tripod and cable release!
