I agree - take Jasper. Sounds like the setting couldn't be better.
I take every youngster I break to the Texas hill country, camp and ride for at least 1 -2 weekends their first year under saddle. I had one little guy that was such a quick learner that he went with me and had only 12 days under saddle!
I go slow and give them time to look around and get their 'sea legs' so to speak. I take 1-2 hour rides a couple of times a day, very slow - sometimes we saddle up, just sit and watch things. There are numerous water crossings/slippery rocks, slopes/slides/switch backs/ uneven terrain from gravel to rocks as big as my head! Campers, bikers, hikers - tents - other horses - deer........it goes on and on!
They all come back with more confidence than they will ever need and when a horse has that confidence, man they learn so quick and just eat up everything you show them after that.
I can't even think of a reason why you shouldn't take him...only reasons why you should!
Go for it - you know you will have fun!
