A guy in the office is leaving the company to go and do 12 months charity work in South America. He's a good guy and we would like to buy him a going away present.
Any ideas what he may want with about a £50 budget, ideally a bit less? He's a pretty experienced traveller and will be spending a lot of time with "locals" so the usual tourist guide is not the option I don't think.
Thanks in advance.
