For a track that copped a lot of flack before states, P.O. is certainly getting a lot of votes....but why??

Reasons for PO are simple, for the majority that work many tracks are out
Frankston because start time is later so for those who have early start and/or travel its a killer, plus many who are doing BSX will find that late start/finish a killer
Knox/Eastfield/South Eastern- races are during the week so if you don't have time off you can't do it.
Lilydale- well the sh!t pit across the rd is reason enough to stay away. Family guy has obviously been there on a warm and windy day before

So truth of the matter is that start times and days that races are held are the reason PO is ahead in the votes. Not all bosses are so flexible with time off to race. the usual response you get is 'Didn't that sport go out with the 80s?' or the most popular 'Aren't you too old to be racing BMX?'
Facilities or the actual track have not much say (except for Lilydale and the SP)
