very cool. I didn't get to ride anywhere in Bentonville besides Coler Park. some big stuff there ("Drop the Hammer" being the most famous). trouble was: a) it was pouring rain, and b) I was alone with only one day to ride. no lifts or shuttles there, and with the wet conditions, it was tough going. couple badasses (driving sponsored sprinter vans, in town to support a XC race up at Bella Vista that weekend) said Coler took a lot of pedaling to keep enough speed for the jumps, so I didn't feel so bad. I wonder if Slaughter Pens is similar.
I can definitely recommend Lake Leatherwood, just this side of Eureka Springs, if the jumpy stuff is your thing. much bigger, steeper terrain, so no problems at all carrying speed (vids are posted around here somewhere...October 2019). they tell you to park at the baseball fields, but I was the only one that did (maybe I'm illiterate). but call them to make sure they have a shuttle driver working the day you want to hit it. DH #5 was my favorite, iirc. there is one xc loop to get you up to the top, but how many laps do you have in you, going that route?
