The River Tolka and its Added Attractions

So I'm walking along the East Wall Road this morning, minding my own business as usual, and happen to look at the River Tolka which runs lateral to it, and I see a burned out Motor Car at the side of the river, just above the water, and I'm wondering to myself 'how the hell did that get there?' so i continue on, to do a bit of shopping in Aldi, and on my way back I happen to look in the direction of the river again, and now, there's a Motor Bike.
