Starting with 28.6.2013 until 30.8.2013, on each Friday at approx. 21:00-22:xx, there will be an evening's inline skates drive through various parts of Slovak capitol - Bratislava. This year it is already the 10th anniversary of the event. The routes will use regular busy roads, with support of city management and police and etc. - hopefully also with the help of Waze?
There are a couple of known predefined routes, the exact one, which will be used, gets known each week some 2-3 days in advance. We have already some available (and are preparing more) lists of known segment IDs to be reused.
