When
my kids saw
East Kennett Longbarrow, nr Avebury,
Wiltshire. Reported 3rd May,
they
immediately saw in it the Pokémon balls that the
okémon creatures come out of! Can you add this
to the comments and see if it opens another
insight? This may not revolutionise the study of
this phenomenon, but it is still meaningful to
young kids!!
