I would prefer to stay with a great old Bristol tradition of the Mum Festival in the fall. This used to be a great annual event with a hot air balloon festival at the same time and our parade.
It was a great time for families in Bristol and Fall brings many events in Bristol like hayrides, pumpkin fields, apple picking, etc. why not hang on to traditions? this is what makes cities special. Could combine with an Octoberfest also?
