Elzo's sheep

Went for a bikeride in the morning close around Delft and then came along this flock of sheep behind this 'flexiwire' ~ it's the fence that got me thinking and made me realise these are Enzo's Elzo's sheep grazing here!
A year ago I'd found these sheep and its shepard Elzo in Wassenaar and then he told me he takes his flock around, like a shepard does, onto the fields in the triangle between Leiden, Den Haag and Delft. Nice to find them on such a different location from then:)

Just found a Youtube film about this shepard.
