Given the figures quoted by Alex, finding a new promoter isn't going to be easy I fear. If you had no Lynn and the Panthers using our track, and still kept their same name, i don't think you will get many Peterborough fans making the trip. Like wise Lynn fans turning up to watch Peterborough. I can't see that working myself.
As said by TTT on here about 3 weeks ago, you maybe could some how combine some of both teams riders and re name them ?
Given how both teams are doing, Norfolk Snails might be a goer
