We just came off a whirlwind tour of Ghana. We visited Accra, Cape Coast, Elmina, and Kumasi. We did all of that in just under a week, covering probably 1000 to 1500 km of ground. Now, that might not be too much in Canada, but in Ghana many of the roads are soooo bad that you are only moving about 20 km per hour.
I don't think I would recommend that, as the appeal of Africa is less about it's sights, and more about it's culture.
Since we arrived in Togo a few days ago, we have been taking it very slow and soaking it all in, which is a much better way to go. It takes time to get to know the people. So, that is when slow is better than fast.
On the other hand, internet connections are painfully slow. Add that to the fact the keyboards here in Togo use a different layout (AZERTY vs QWERTY), and typing out a simple blog post becomes quite a painfull affair. This itty bitty post you are reading just took me 30 minutes to write... meanwhile I think my lunch isn't agreeing with me so I gotta jet!
