Yesterday I joined for the first time the monthly biker celebration ride that is being held since last September in Cluj-Napoca as the local critical mass event. It was a nice 15 minute ride of approximately 60 bikers around the city center. It is happening on the last Saturday of every month, and will probably attract more people as the word spreads and weather turns warmer.
Unrelated to biking here's a very clearly presented 20 minute flash movie about consumption, suitable even for children http://www.storyofstuff.com/
Seeing this, and the recent news of China banning plastic bags prompted me to start reusing the existing plastic bags when at the market, and asking the merchants to not bother giving me a new one for every single item. They would just pile up and be thrown away after a single use, wasteful even though non-obvious.
