I forgot to mention the other C182 that's also for rent. The REG is V5-JRW. Its the owner of Immenhof Guest and Hunting Farm. Very good friends of mine work their and all of the management staff are all Commercial Pilots. So I dont thing you will have any problem chatting with them. You might even stop over to have some lunch their. They also have AVGAS on premises. They dont really sell but Im sure in real emergencies they will gladly help you, like they did with me last time. Dont have their number handy but they are definately listed in the Namibian Tourism Bureau.
Good luck and keep us posted!
