Search shortcuts for marijuana marches (add city name). First link is for searching Youtube. When you use one of the Google web searches, you can then click other links to search Google News, and Google's video search. It searches more than just Youtube videos.
Click (or right-click) the search links. Then add a city name, and search again. Remove or add search terms to find other events, and other cannabis-related videos, pages, and images.
The higher video resolutions available via the settings button under most videos (at their source pages especially) sometimes also increase the audio quality of the videos. On embedded videos you can click, or right-click, the source links to go to the source page to watch the larger versions.
