That is the correct answer, maybe you typed it in wrong? That
happened to me when I did the kimball library box...typed in the
correct answer wrong, got an error message and instead of carefully
typing it in a second time I started trying all sorts of other
possible answers and got off on the wrong track. About a week later
I looked at it again, typed in my original answer and it worked!
This is the URL I used and fo tto the last challenge...you have
probably already gotten there yourself.

If you have not solved the final puzzle, I am happy to give you a
hint...it took me about half an hour to figure out solving the
entire thing would take forever but there is a trick.........

Here it is Sunday eve and never made it to Cloverdale...we decided
to go to the beach instead and it was gorgeous! One of the nicest
days at the beach I can remember. I did go check on breaching
whale/SeaCreature #4 and found it right were I left it. Two other
people had too...and I noticed some definite footsteps up to the
coyote bush....so I need to move that box to a better place that
wont damage the vegetation. Not a very good place to begin with but
it was a rainy day and I was running out of time and just wanted to
find a home...so if you are ever out that way again and go for it
recheck the clues because they will change. That was my only
letterboxing experience for the weekend.

But I did get alot done in the yard! I was even thinking of
planting a drive by letterbox in my front yard, but that might be
too wierd for people!
