beyond the wide world's end

Cambridge has excellent rail links with London, so if all else fails, I can come down and visit you on a free evening! Also, there is The Globe. We must compare calenders. (What are you doing on the morning of the 4th? Being jetlagged and burdened with luggage, a swift trip around the BM would probably not be a good idea, despite its useful position in relation to King's Cross Station.)
