My husband & I vacationed in Estes Park & when I told the (adult) kids back home that I wanted to do this they laughed, as I am afraid of heights. Jokes on them, I did it! Of course, I never got beyond the first 10 foot high level, but for me this was quite an achievement! After our introduction & training, they let us loose. Staff were always watchful & kept a close eye on me, talking me through manuevers when I "got stuck". At one point, I needed assistance because my legs just froze up, but it wasn't made into an embarassing event & I was soon off on to another set of challenges.There were plenty that I could do. For an out of shape, low lander couple in their 60's I think we did all right! Of course, our bodies protested the following morning, but that's ok, we were flying home. Only regret: we didn't get pictures! You can't take pictures if on the course (in fact pockets are supposed to be empty) but if you bring someone along who stays on the ground, they can helmet up below & take pix of your dare devil adventure! Suggest reserving an early session before the heat of the day & the afternoon rain.
