This year the
NASS festival in the UK is going to host the iBMXff World Championships again including flatland. Quick reminder: iBMXff = International BMX Freestyle Federation which is more or less the most official organization that BMX Freestyle has to offer ;-)
It's schedule for the 6 - 9th of July near Bristol. There will be all kinds of BMX and Skate contests as well as a music festival. More details and links:
