A Hippie friend of ours rode her horse Scotty to Glasto from Surrey about 4 or 5 years ago in a real traveller way, she just rocked up to farms along the way and asked if they had a spare field for her horse and just slept under the night sky with him!!! It took her over a week though and after the festival the last thing she wanted to do was ride home (got picked up in the end)!
