Exactly my plan for the last 10 years.  But in the highest
density APRS network in the world (Wash DC/Baltimore area) the
number of active live human operators at FD sites that I ever
contacted I could count on one hand. (That's with over 100 clubs
in VHF range)...

At least in this area, APRS is lights on, nobody home, trackers
blindly transmitting, D700 operators driving around never
reading their messages or clearing their buffers, (me
included)...  Most people with Voice Alert off, because a
live-aboard boat in downtown baltimore leaves his D700 on voice
alert 24/7 and drives everyone off for over 100 square miles...

Same in Washington DC.  Someone leaves their radio on voice
alert-nobody-home 24/7 so you just have to turn it off.  

Most of the home stations are running Uiview with no PHG data,
so you cannot plot their antenna coverage areas and therefore
you cannot easily visualize house-to-house paths through the
non-digi network.

Over the same 10 years, I have never seen anyone in this area
put up a temp digi for FD, or do anything other than park their
D700 at FD, and make a contact from their FD portable to their
car, claim 100 points and then shut down.

Hence, I give up trying to get people to actually communicate
via RF live as humans, using temporary paths and temporary
digis.  The alternative is to let APRS continue to be the
"side-show" with no real application as perceived by the FD
contesters except bagging those 100 points and once a year
tracking trackers at special events, and go home...

Sorry to sound pessimestic.  I hope it is better in other areas.
I have see some live humans at FD sites in NJ and VA..
