Belize City is very interesting. If I had but a day there I would call Edgar August, taxi driver and a fine fella.
Edgar can be found hanging out with his cab at the Raddison or just ask for him or look him up in the phone book.
Tell Edgar what you are interested in and he will help you get around, shopping, sightseeing and history. If you have time he could even take you to a jungle lodge for a luncheon.
Belize City has made terrific advancements in the past half-decade. The city is much more clean and the people welcome you graciously.
If you do contact Edgar, tell him Dr. Ray said hello
