We are looking forward to visiting Panama with Overseas Adventure Travel in early March, which is part of the dry season. Can anyone tell us about the mosquito situation that time of year? We will visit Panama City, Cerro La Vieja, Gamboa, and the Canal. Will we need to keep arms and legs covered at all times? We've visited Central America, but not Panama, at this time of year, so we'd appreciate your opinions. Thanks very much.
