Hey Jon, <br />Glad to see you over here.. <br />I was just thinking about it and came up with an idea. Attach some monofilament line to a tie where it cross's the gap in the blocks. Run it down the crack and under the block. Pass it back up thru the next crack and attach it to the tie at that crack. You might ge able to silicone the mono to the bottom of the tie so it wouldn't show. That would keep the track from going anywhere and still let it move for expansion. <br />Just an idea!
