Every time there is enough money in the bank, it has to be exhausted soon. I have travelled extensively in the US and Canada (including visits to half-a-dozen national parks), Kenya, Tanzania (Oh!Ngorongoro!), Seychelles, Far East, Continental Europe (including schizophrenic Turkey) and quite a bit of India.
I focus on budget trips, with an accent on nature - hiking, camping and the like. I am a member of the WWF - World Wide Fund for Nature and go on trips with them.
