Ha, the OLS! That really is a big event in the regions where I was born almost 30 years ago.
Great to see Beatrix and Filip together at this joint Dutch-Belgian gathering of good old folklore. Personally, I don't like the Schuttersfeest at all (seen too much of it through the years, I guess) but it's a tradition that should last till the end of days for the tuns of people in Belgian and Dutch Limburg who obviously love it! :p So it's good to have some royal attendance from two countries. Lovely to see how the Queen and the prince really seem to get along!
