Dave,
Gillian & I have contacts in the Czech republic through the twinning, our partnership town is called Richany which is quite close to Prague and Richany, has a partnership in Poland called Opatowek, about 5 hours away by car, which I am hoping to ride to sometime round about March time, when the weather improves, I have been invited there by the Mayor, who I got on with very well on my last visit to Richany.
If your planning any trip that way, let me know and I will see if I can organize anything for you.
Regards TTJohn
