Will be arriving in Vietnam May 11th by Honda Win @ Tay Trang border crossing from Laos. I'd love to see the north of Vietnam, Sapa region in particular, but I've heard mixed reviews about the weather. Would love some advice from a rider? Is it advisable to ride a motorcycle in the north in May, or too much rain? If so, I'll consider heading from Luang Prabang to the Na Meo border crossing instead of going farther north to the Tay Trang. Thanks in advance for your help!
