I came across this info in the Casa Luna Newsletter which might be of interest to others:
Jalan Bisma is now being paved with cement blocks, similar to those that lie outside the palace. If you want to be a part of Ubud's history you can buy a block. They cost Rp.250,000 each.
We are going to buy one for my grandson to commemorate what we hope will be the first of many, many visits to Bali.
