well done that was great.......just wondering how long did it take you to be able to do that?
There's a short answer and a long answer to your question. The short answer is that Tucker became my Parelli levels horse (the one I focus on while learning Parelli Natural Horsemanship using the old study-at-home levels packs) in late 2004, and I took the bridle off for the first time after reaching Level Three in late 2006. This video was taken last summer.
The long answer is that I've been riding since I was 9, and was introduced to natural horsemanship (not Parelli, just generic NH) when I was 19. I'm pushing 40 now. I don't feel like I made huge strides in my horsemanship while riding until starting with Parelli, though I learned a lot about groundwork from other NH sources.
Of course it's not set in stone, but I feel it is totally reasonable for a fairly fit and athletic individual with an uncomplicated horse (that part's important!) to reach Parelli level 3/4-- and bridleless riding-- in 3 years.
