If you are on the budget bush camp is your best friend.
2012-2013 I rode around on R1100gs 23african country's and bush camp 95%
Back of Police stations,catholic missions,fields,farms,beaches,abandoned houses
Warehouses,it's very simple,late evening (most of the farmers are home)shortly before sun set,look for dirt road,bicycle path,ride away for couple km,from main road,look for flat place for your tent,if you can't find place,ask people (use your body language)
If you can sleep on their property,most of them will say yes.
Make sure is free "no money" otherwise you will have surprise
Dangers animals in Africa? Most of them are killed and eaten rest of them are in national parks,

Small hammock with Mosquito net is very handy if you can't find flat place to squat.

New Year's Eve 2012 in the middle of Cairo,amazing person took me into his home and slept with his door open next to my tent.
Some times in the morning you may have local visitors,every one super friendly,locals have deep respect for overlandes.
