If this is really happening I would have a suggestion (at least if people come already on friday). It is a tradition to go to check the flee markets very quickly and on the same trip we could eat lunch in a very very good pizzeria. Best pizzas I have had in Finland. The recycle centre (if open) would be just a quick stop but everything is free there, so no charge of anything. Then there is Tuohitori which is a very big second hand one and I have sometimes made nice finds from there. But again just a suggestions. And near in Kauvatsa is also a Gulf gas station and on the way there is a small home cafeteria which owns an ex motorcycle racer who has a big collection of two wheelers.
