The American Veterans Traveling Tribute arrived in Johnson City on Monday.
The event will commemorate everything from WWII to September 11th first responders.
A highlight to the week-long event is a half-scale replica of the Vietnam Veterans' Memorial in Washington D.C. Organizers are expecting up to 50,000 people to attend the festivities at University Parkway Baptist Church, including many veterans.
The free event kicks off on Tuesday and will continue until Saturday.
Tuesday's events include a blood drive from 3:30 to 8 pm, a special appearance by the EMS Honor Guard at 5 pm and a Carter County Sheriff's Department SWAT Team demonstration at 7 pm.
