When you exit Shannon Avenue, drive onto Marnock Rd until you pass the old mill. As you head towards the public toilets, especially near the car park you should see some action. There is also another small car park just close to the river. If you go back on Marnock Rd, take your right turn into Riversdale Rd. Drive on and make your right turn into the car park. From 9pm you should find people here.
