Letty - A happy new year to you, and thanks for the organizing. Does the offer still stand for a place (180 x 80 cm) to roll out my mat? I still have not looked up the timetable for my trains; if it's a long distance I might arrive in the evening hours of May 1, if it isn't inconvenient. I think I will bring my bycicle with me, because the Netherlands are so wonderfully flat. Unfortunately there is no plan of Groningen in the official website. Is there anyone elsewhere in the net?
