I'm taking a two-week course in London this summer, and I'd like to spend my one free day (a Saturday) visiting my grandfather's hometown of Bolton, Lancashire. What's the fastest, most cost-effective way of reaching Bolton from London? Also, with only one day to take it all in, what should I visit (besides the house he was born in!)? And lastly, what's the name of the local newspaper in Bolton? I'd like to post a letter in the hopes of drumming up some possible relatives to visit. It's a long shot, but it could pan out.
