Chance at Africa

My wife has a chance to explore Africa in September 2018, something that she has always wanted to do.  So far we have put away half of what she needs and the rest is due in July so I thought I would reach out to my friends, family and anyone else who might want to help out.  A definite "Bucket List" for her.  Any donation would be greatly appreciated.  I want this to be a surprise so if you know my wife please do not say anything to her about this.  Thank you in advance.
