You won't be sorry! I forgot to mention that a lot of the club membes are selfbowyers also. Gary usually brings lots of staves, from the easier, straighter "beginner" staves to the tougher "character" staves. Mark usually has some cut off the property also--prices range from cheap to not so cheap, depending on the stave.
If at all possible, I'd get there early--like Tuesday or Wednesday if you can swing it. By Friday/Sat the place is swamped, and it's harder to get a spot at a vice, or in the hotbox, or get as much one-on-one help. Every year there are even kids that make a bow. Even I made one year before last (with a lot of adult supervision). If you want, you can compete in the "Selfbow Challenge"--a separate competition where you compete with the bow you made that weekend. I lucked out and won it with the first (and so far only) bow I made--that one is probably my favorite trophy.
