Just checked on FB now, here's what the update says on their page:
In a few hours over 250,000 people have seen and commented on this last post about the zoo being opened for FREE for the winter to EVERYONE. I decided a few years ago to thank the loyalty of our visitors and to give opportunity to those less fortunate in our communities by GIVING the GIFT of a free visit during the winter months . It has brought the zoo's mission of conservation closer to millions of hearts and allowed us from all the donations given on entry to make a huge difference to wild animals and remote communities throughout the world.
It is MY PERSONAL present to you all.... so come and enjoy our zoo and dont forget to spend in the restaurant /cafe and shop and donations to our work are gratefully accepted... Have a great time and thank you from my children and myself to you all for the wonderful support you give to our mission to not just talk about conservation but to DO IT ! See you all soon...
