YouTuber Ryan Trahan and his wife Haley Pham are attempting to stay in each of the 50 U.S. states over a 50-day period. The challenge is a fundraiser for St. Jude, and nearly $500,000 has been raised in just one week. 

The videos are on Ryan Trahan’s YouTube channel titled “I Tried the Top 50 Airbnbs in America.” The couple ranks each of the places where they stay. Thus far, they have stayed in Texas, New Mexico, Arizona, Nevada, Utah, and Colorado. 

Although the planned route is kept secret, Trahan and Pham will likely reach the New England area sometime in July, if they continue in the challenge. In Maine alone, there are over 20,000 Airbnbs for the couple to choose from, according to the Bangor Daily News. 

Viewers can interact with the series by donating, as high donations trigger additional challenges for the trip. Donations to the fundraiser can be made on the St. Jude website.
