I dont see why Dalry couldn't get an u20 team - Many of the boys that attend Dalry games on a Saturday are 18-20 and many of them are outstanding football players. I'm sure the interest is there. In my experience, once I hit a certain age there was no team in Dalry to play for - I'm sure a lot of boys feel the same and would love to play for their town.
I also believe the full system in Dalry is being revamped for the future. I've heard that all of the current Dalry teams will be renamed to Dalry Thistle with a couple more being added for a direct pathway (boys and girls). Don't quote me on this tough - although it did come from one of the dads it could just be chatter.
