This is exactly why i'm an advocate of the SoSFL merging with the WoSFL in some way (as a Div3 or 4 South).
Nothing against the SoS, a good league, no doubt run by good folks for the benefit of clubs in D&G. But its presence at Tier 6 potentially could doom my club.
A responsible and proactive governing body would see this, get folks around the table and sort it.
