The Fort Worth Valley does degree work a couple times a year. I am getting the degrees this month, and they are all being presented over 3 Saturday's on 3/5, 3/12, and 3/19. The 1st day was the 4th-17th Degrees, the 2nd day will be the 18th-28th Degrees, and the 3rd day will repeat the terminal 4th, 14th, 18th, and will confer the 29th-32nd.
The 3rd day is technically considered the "One-Day" program, as it represents only the terminal and final degrees, and so you are not required to attend all 3 days of the Reunion. Attendance of just the last day is considered sufficient to complete the degrees.
I put off joining the Scottish Rite until now because I wanted to see all 29 Degrees presented individually. I highly recommend doing that way instead of the "One-Day," as each degree has tremendous value.
