I’m calling this a mini review because I have included some images from the books I am referencing. Just last year I invested the $70 to get the two FunTreks Colorado books and I was checking off the trails and having a good ol time. Then last week I pop into the local outdoor store and there are two brand new editions-2019. I waited because I was a little annoyed that I had just bought the now old versions. I thought about it though and I am really doing the trails and we had major floods since the last books and I actually ran into at least one trail that was no longer as long as it should have been. So I went back to buy them and they were sold out of the regular one so I just bought the northern Colorado one. All my annoyances were assuaged when upon finding the first full page color photo was of—-a gx! Then later on there’s a pic of a 460 on one of the trails. Then again (it’s the same pic from inside) the gx is actually on the back cover. So there is some gx representation that is cool. Aside from that which is cool for us, there are new trails and updates to the old ones with references to keep the old one because they changed em up etc. I haven’t scoured the other one yet, I found it at a local Offroad store but no gx’s right off the bat. Also new sections and updates so overall I’d say worth a buy even if you just got the 3rd edition.....it’s funny too because the author got a Tacoma and overall there is way more Toyota’s in general
