Had reason to drive to Tongwynlais this morning, 20mph for about 5 minutes, then 50 down to
40 on Eastern Avenue, 30 on Manor Way, 50 on the A470 culminating in 20 in downtown Tongwynlais. Where is the 20mph blanket law that some keep banging on about the areas that were 20 were sensibly categorised I reckon.
