A plan was for us to maybe build onto another side of our place, believe Historic Scotland objected though, to a structure facing 'their' Castle. The road down to The Rock being a dead-end also hindered plans for a bigger capacity, only 1 access route or something.
To be honest, Dumbarton FC's ground has been full only a handful of times since construction.
I agree though, I would love us to be in at least a 2-sided Stadium, no matter how small.
