  After Trico we headed by Train to Pollonaruwa (where we didn't have coackroaches! :)), to be told on arrival that it was 36 degrees.
The next day we went to the ruins early, 8am, to miss the heat. We went out to all the Northern sites as well as the central ones which required a bike ride of about 10kms all up. The whole round trip took us 5 and a half hours. The ruins were amazing though, some of them were still amazingly in tack and it was mind blowing to imagine people living there around a thousand years ago.
I won't bore you with a blow by blow account of each site. My favorite was the Tivanka Image House which is was part of a monastery with an absolutely huge Buddha in it. Also, the Lankatilaka was great which has a cathedral like aisle leading to another huge huge Buddha and the outer walls were decorated with bas reliefs. In the afternoon we went to the museum - it was around 40 degrees - which was great with lots of statutes from the ruins and models of the sites.
We also had a chat with one of the guards there who had AUD$5 he wanted to change into rupees. He also stated that when we returned to Sri Lanka next we should bring out our little baby with us and that we shouls start practising the process now!!!!! I laughed heaps - however Jonno went pale and I thought he was going to be sick...... :) What a crack up....
