I had seen the St. Patrick Day Parade in the past and it is so colorful. This year I am thinking to take some pictures. I never shot in this kind of event. Any advise from lens choice to technique is welcomed. I promise I upload the pictures for you guys by Sunday. NB - I am using Canon 30D and I have the 28 - 135mm (kit lens) and 50mm f/1.8. I can easily rent other lens if this is not sufficient.
