anyone interested in doing this year's st patricks day harbour to harbour aware charity walk? you can start either in howth or dun laoghaire. the walk is divided from each harbour to dublin city center and then to the opposite harbour, which is about 16 miles. you can also choose to only do half the walk (ending in city center) if the full 16 miles is too much for you. registration is €20 for one or €30 for a team of two.
