I can't say it enough. Get there on time for midday. If you're stuck in traffic though, that's a bummer. It's often good to check with Bristol City Council's website
to see if the silly buggers have a " fest
" organised ( which shuts down, traffic, sections of city or many other facilities desperately needed by mountainbikers which for the day are given over to bloody kite flyers! ). When I ( dis ) organise it the jumble usually lasts about an hour and a half. Please don't be too dis-chuffed, I'll be doing another next month ( ...and another, and another ).
