Peter Neilson's account of life on the road was spot, and yes, Peter,
there are others who do it!  Here in the UK I have been dragging a
player around for the last 6 years or so.  Here are my equivalent
reasons for not doing so:

Rain.  The piano is not happy with bad weather, the rolls even more so.
I could not agree more.  And rain always waits until you have the player
half off the trailer before soaking you.

Sunshine.  At Sunny Swanage I noticed the keys starting to curl.

Shyness.  I don't even attempt to sing.  I leave that to the show-offs,
or the professionals -- the whole of the Savannah Jazz Band joined in
to sing "It's a Sin to tell a Lie" at the Queens Hotel, Keswick.
Magic!

Wrong Roll Syndrome.  Definitely to be avoided.  I once started on
Schubert's March Militaire by mistake, but I had to finish it.  Funny,
though, whilst some folks disappeared, others drifted in.

Weirdness.  The pianola is too weird for teens.  Yes, but they cannot
help taking a sly glance.  Definitely no questions from them, though.
5-10 year olds are a different kettle of fish, however -- you can't
keep them away!

Competition.  Starting a roll just as the band are just about to play
again after their break is always amusing.  (Well, it saves them a
number anyway.)

Self-taught musicians.  I make sure that only band musicians are
allowed on my players.  I regard their interest as a compliment.
Especially when they say they prefer my piano to the venue's own
instrument -- not uncommon!

Muscles.  They ache the next day.  From pumping?  No, from putting the
piano back up into the trailer.  I have developed techniques over the
years to minimise this.  I now do it on my own using blocks of timber
and a board to construct a movable ramp down which my dolly rolls a bit
at a time until the player is fully lifted on board.  Takes time but it
is safe.  Then I trundle it all up to my home-built trailer which is
marginally lower than the dolly.  Roll on -- Roll off!

Danger. The piano hasn't fallen on its back yet.  But there have been
a couple of almosts.  Me too.  Mainly from slopes -- the enemy of the
piano mover.  Not up or down slopes, but the sideways kind.

Ears.  After a week long festival I temporarily lose all interest in
piano roll music.  That is until the next one.
