Me, too, I have often used sheds and the like.  So, there you go, Walt, 
carry a concrete shed with you.

Seriously, my very limited experience with Spadefoot Toads, Scaphiopus 
holbrookii. (DelMarVa, 1956) indicated that they only breed during, and 
shortly after, unusually heavy prolonged showers.  The chorus time after 
such deluges may only be a few hours long.  What luck have you had in your 
surveys with these elusive, fossorial creatures?

I see from your web site:

http://wwknapp.home.mindspring.com/Docs/eastern.spadefoot.toad.html

you have nice, clear recordings of "the grumbling old men" from one (two?) 
location, but they have always presented survey nightmares, because you 
almost have to be in location BEFORE the deluge to hear them.  Or else, you 
find them in wet basements by word-of-mouth (This Broken Archipelago, J. D. 
Lazell, Jr. 1976, 'Spadefoot". p. 101, NYTimes Books, Quadrangle Press.)

Prior to spraying for mosquitoes, they used to be common in much of 
southern New England.  In 1974, I had John Q. Adams (the great grandson!, 
then 91) show me three locations in Lincoln, Mass, where he heard and 
caught them as a boy near Mass Audubon Society (around 1900). Now all gone.


my very best,
