Pick-your-own fruit in the Cologne-Bonn area

Just returned from v. successful strawberry hunt, so thought I'd post a spontaneous tip for all fresh-fruit lovers out there. 'Beller Beeren' - just south of A4 between Koeln W. & Koeln S. junctions currently allows 'Selbstpfluecker' (careful how you pronounce this) onto its strawberry fields. Paid under 8 Euros for 4 kg - about half the going rate in our local supermarket.
We found a place last year doing PYO apples (in October, I think) - can't remember the name at the moment, but it was in the Eifel direction. (Can also recommend a 'chainsaw-your-own' xmas tree place nr. Bruehl, but this can wait for chillier times).

Naturally wondered whether anyone else can recommend some good farm shops.

Iwent strawberry picking yesterday, also picked 4 kilos ,put them in the freezer for winter, they taste great when its so cold outside.
