Another long, but fun day touring London. We left the hotel this morning at 7:30a.m. and have just returned at 10:45p.m. We are exhausted. Much of our of time today was spent on public transportation. London is a nice place to visit but we would not want to have to get around here on a daily basis. We leave for Zambia tomorrow night and will arrive at 7a.m. Zambia time, which is 8 hours ahead of CST. Once again, please pray that we have a safe journey with no problems through customs and immigration. And that all the luggage makes it!
