Do i need anything before heading to Zim?

I'm heading over to Zimbabwe in August. I've been doing my research but still have questions.

1. Do i need a Visa to enter the country? Do i have to get that ahead of time or upon entry?

2. Any suggested inoculations? I will be on a malaria preventitive (not sure which one yet). Any other suggestions?

3. I'm not taking a rifle so i am not necessarily worried about that. I will be taking my bow though. Anything special i need to know about that?

4. Any advice or tips from people who have been there?

Thanks in advance.

TOM, here is some information to get you started, click here.

Thanks Jerome. I've looked through that and it has answered several questions. Still any suggestions would be appreciated.

Yes, don't go this year. It will be worth your wait to go next year. Yes, the buffs will still be there next year!
