I'm one of the guilty ones.  I have hidden just under 1% of those I've 
found.  However, nowhere that I've seen am I required to hide a cache in 
order to find them. Four out of five of my hides are quality hides-- not 
'stop and drop' like so many others.  The fifth one, until it was 
stolen, was a unique hide and difficult to find so, it was a quality 
hide too, in it's own way.  I will hide more but I would rather see 
people hide fewer caches than to see them hide more than they can 
reasonably maintain.  Remember, that is a responsibilty the hider needs 
to assume.  Not just to flood an area with caches that he/she cannot 
possibly maintain (until somebody complains that it is missing.)  As for 
not enough caches in Arizona, I think that is poppycock!  I'll make this 
promise to anyone who is reading this.  The day that someone (anyone) 
logs all of the caches in Arizona, I will go out that week and hide 20 
new caches!  Anybody up for that challenge?
