This is the best summary I could come up with:

On and off for the last seven years, the Rolling Barrage cross-country motorcycle ride has come to the National Capital Region to raise awareness about post-traumatic stress disorder (PTSD) among military veterans.

One year later, Casey launched the namesake ride, "for combat veterans and first responders, [to] specifically create peer support right across the country for those people and their families."

The origin of the other motorcycle group, Rolling Thunder, can be traced back to the truck convoy that occupied downtown Ottawa two winters ago.

Sheard gained prominence among convoy supporters in 2022 after he appeared on a social media video stream calling for bikers to come to Ottawa's National War Memorial for an event organized by Veterans 4 Freedom.

At a press conference last month, Ottawa police Chief Eric Stubbs referred to this iteration of the Rolling Thunder convoy as a "protest."

"The Ottawa Police Service will monitor public safety and will be present to ensure the safe passage of motorcycles through the downtown core," the media release read.

I'm a bot and I'm open source!
