We spent the New Year at some Hot Springs in the north of Nigeria - a small river flowing out of the cliff, clear, clean, and about blood heat. Very nice. Then on to Kano, a major city in the north with a magnificent central market covering several city blocks where a guide is absolutely essential if you are looking for something specific. Beautiful indigo-dyed cloths from the central dyepits that have been operational for centuries - West African trade beads made in Venice 300 years ago for the slave traders - wax-dyed cloth made in Holland and exported all over West Africa for their (now-)traditional clothes.
Street stalls selling strong coffee and sweetened condensed milk made by Nestle, who have a massive presence throughout West Africa.
We were noticing the Hamatan by now - the dust-laden north wind carrying sand from the Sahara desert and covering everything from clothes to eyelashes with a fine white dust. This is a seasonal wind, and ruins the otherwise nice living conditions of the sub-Sahel region.
Then to Lagos, a huge, sprawling city with suburbs and shanty-towns that spread for tens of miles north, busy and rumored to be dangerous though I had no trouble. I visited the University for something to do, and was very disappointed in their computer department.
