Look after a rain in a shady area, look the day after, they grow fast. I believe the rotting bark of the elm tree is a favorite spot. If you find one stay in that same place for a while and focus. If you found one there is almost certainly more around and they camoflage well. It will look as if there are none there but all of the sudden they will be popping up all over. It can be deliciously magical. Be careful to rinse sand off carefully. I don't know the proper method for cleaning them but sand in the mouth is very unpleasant. Tradition dictates that you take the location of your spot to the grave. I sometimes tell.
