Park along side the road and enjoy it, but when they put up signs or change the use of this road side parking don't bitch and moan when you need to continue driving into that park and pay your fees. If the parking situation creates an issue they will modify your behavior or it will cost you in a larger fee.
I can only speculate that this road side parking will be changing in the future and it won't be Metro who will be driving the change but the Interlachen community will be at the helm.
Keep an eye on the meeting minutes on this website
I always play through groups starting on Hole 8, Why should I wait on you when I have paid $5.00 to play you freeloaders!
