Collecting Frog Spawn

A Polish friend, whose kids are at school with Tiger and Cricket, suggested a trip to T' Zand in Alphen where there is a large swimming lake - just for a run around as far too cold for swimming.  The children were on a free school day.  What a gorgeous area to go walking and of course to swim in the summer.  We found some frog spawn and collected it so that we could watch the frogs develope.  Husband has never been less impressed.
