Brendan,
I think I found the perfect activity for Mr. Mendoza when he's visiting the Honolulu offices next month. Check out this Web site: www.oahusharkadventure.com
This might seem a little extreme, but we all know how much Mr. Mendoza loves the ocean and scuba diving. We bring him scuba diving on every trip he takes out here. But I also know that he's fascinated by sharks. The last time he was in Hawaii he was reading a book about them and would bring them up in conversation every chance he had. So I think this would be perfect for him — something different but something he would enjoy very much.
My brother-in-law went on a shark adventure through Oahu Shark Adventure when my sister and her family came to visit me last summer. He said it was very safe, very well organized, and an experience that he will never forget.
So what do you think？ Perhaps we can discuss the idea with the whole team on Thursday. We can find out if we have any volunteers to go on a shark-viewing adventure with Mr. Mendoza — if we're all in agreement that it's a good idea.

What information does the advertisement provide？
A．A list of prices
B．A schedule of times
C．Recommended sites for visitors
D．Equipment and experience requirements
