We have a gypsy family (one of many housed here in the village) who are often seen driving their 4x4 pick-up, with a kiddie sitting on a bale in the back and holding on to a coloured cob which is happily trotting steadily behind.
Now, I know it's not exactly the done thing, but these ponies and cobs are completely traffic proof, child & dog friendly and very fit!!! Only thing I really worry about with these people is that they start them off far too young IMO.
