Please fill in your availabilities for our third common math hike in elu-participants. There are four specific columns for that and for each day you should write the time-frames when you can play the trail at its location which is not far from the location of the previous trail but not too close either. Free parking is available close to that trail eventually. That trial is created by one of our known authors and the topic is also similar to one of our past ones. i have chosen these days because katriin is going to be available during these days.
