I think it is one of the harder if not the hardest in Northern Utah, can't rightly think of a legal trail that is harder?
When we first forged Constrictor it was no doubt a much harder trail than it is today, in fact in the very first few runs of the trail there were few that drove it unscathed, and nobody could even get close to driving the 'Eagles Nest' (a fun story behind the naming of that anyways). With more use it has mellowed out significantly over the years, obstaces such as Radiator Rapids, the Fang as well as the Eagles Nest have all been worked over pretty good. To be expected with heavy use really.
Still trying to rack my brain as to a tougher trail in the northern state?
