It's a fair point that some people work on Saturday and can't walk. Some of our guys have to occasionaly travel up from South London on Sunday morning as well but we do try and get most guys up Saturday afternoon to walk the fields. Some is better than none.
I have to say I don't feel it is the tournament organisers responsibility to provide time in the morning to walk the field if it is going to impact the timing of the event. If they can offer more games for an earlier start that's fine by me
If teams want the advantage of detailed field walking they need at least 20 minutes on each so a morning walk of only allows a cursory glimpse to decide who goes where on the break anyway. If teams want an advantage and to progress up the rankings they need to find their own time to walk the fields properly. Wendy does her bit by making sure they are available on Saturday. Having said that it is getting lighter now so should allow for peole leaving home later.
Again I suppose it makes a difference on your motivation for going. For some people it's justa day out with mates playing paintball which is fine and this obviously hits them harder but for those taking it more seriously and wanting to compete it should be welcomed. I can feel a whole discussion coming on so I'll stop now.
