We (my girlfriend and our three kids, my sons 12 & 11 and her 9 year old daughter) participated at FE last Fri (11/ 23/12--the day after Thanksgiving). My girlfriend and I took pix/videos of our children's activities--we did not actively participate.
All three of our kids did the kids' course. My 12 year old was borderline, but due to self-confidence issues, I emailed the owner (Paul) several times during the week and he agreed to let my son go on the children's course. In retrospect, I have mixed feelings about this decision (which I alone made), but more on that later.
First of all, we all had a great time and this is an excellent venue and terrific value! We will definitely go back again when the course re-opens in 2013--this time the adults will participate too! The course is easy to find, right off of I-17 just south of Flagstaff. I wish they served/sold hot coffee/chocolate there, as I had to dispatch my girlfriend to the nearest Starbucks/McDonald's to find us some, as it was a bit chilly early that morning. But I digress.
Our two youngest (my son turned 11 this month and her daughter turned 9 this month) had an absolute blast on the course and were basically racing thru in on their second and third iterations--they can't wait to return!
My 12 year old is approx. 5'7" and was probably too tall for the course. Again, this is my fault, as I requested special permission from the owner to have him participate on the kids' course, as I thought it would be a boost to his self-confidence. In retrospect, I think the course is geared to smaller, shorter kids and as a result, he had some issues with several of the obstacles, causing him to get somewhat frustrated, and increasing his feelings of self-doubt. I asked him if he wanted to try the beginner adult course (I would have gladly paid the upcharge as well as admission for myself) but after he finished the kids' course the first time, he was done for the day. I'll try to get him back up there for the adults' 1/2 course, but I'm not sure that he's interested. In any event, this is entirely my fault, not the owner's/course's.
I highly recommend this activity, and as I previously mentioned, we'll (at least 4 of us) will definitely return again soon!
