We've had a mention (along with the very worthy Pets' Corner!) in the MEN.
In an article listing "The 11 Best Family Parks in Manchester" disc golf is mentioned under the write up for Longford Park!
There is also a newly installed disc golf course - basically golf with frisbees, which you can either take along yourself or hire at the park. The course is still being completed but is available to use and on the first Saturday of each month the Manchester Disc Golf Club holds sessions showing people how to play.
