Operation Comfort and Help for Heroes are two organizations from the United States and Europe that raise funds for their Veterans in their respective countries.  These teams visited Viet Nam to ride their bikes over long and often mountainous terrain to raise those monies.  Two of the riders had each lost a leg in the wars in the Middle East.   One lady had her husband loose both his legs in the same wars.  We met them in Da Nang and travelled with them from Marble Mountain on the southeast to Hai Van Pass on the northwest of the city.
