I miss my day trips to Macau. It was easy to get there from where we lived in Shenzhen--a twenty-minute bus ride to the ferry terminal and a little more than an hour to Macau (or we could've stopped in Zhuhai and walked across the border). I'm not big on gambling, but it was fun to walk around the casinos and see the difference in culture to that of Atlantic City (no one was getting drunk at the tables in Macau). I enjoyed wandering the colonial streets and parks. I always seemed to have good weather when I made those trips.
Of course, the first trip to Macau required me to take in all the tourist sites. One of the first stops was the ruins of St. Paul's. It is a rather impressive facade that remains, and the view from the steps is really nice.
