Dear Locators, I am organizing the Location stream at the 60th Annual Conference of the OR Society that will take place in Lancaster, United Kingdom, 11-13 September. This is a very special edition as it is the diamond anniversary. I would like to invite you to submit your abstract on any aspect of Location Analysis at http://www.theorsociety.com/OR60 *Deadline for abstracts is May 31.* Should you have any question, do not hesitate to ask me (sergio.garcia-quiles@ed.ac.uk). I look forward to seeing you all in Lancaster in September. Best regards, Sergio. The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.
