We ride in West for a week most years. We used to have a "park ride" on Wed or Thurs, as a break from all the digging out we did outside the park. (You know, when a 144"x2" was a lot of track...) I really liked those rides, and it was nice to just be able to get in and check out a geyser or hot spring area, walk the boardwalk, and perhaps get some food at Old Faithful. I miss those days, and I'm 100% opposed to the way the park was closed to snowmobiles in 2013, as I could not identify any sort of real "problem" at the time.
That said, I can't imagine what a total disaster an open park would be these days... There are WAY WAY more people riding now, and with too many people comes too many a$$holes... The park speed limit was 45, and I got absolutely blasted by some asshole doing 80 every time we rode in the park, particularly on the long ride back to West... Given how people ride the trails today, I think that it would likely be an un-manageable problem...
I WOULD like them to ease up on restrictions for self guided tours. Perhaps double the number... And get ride of the stupid "latest technology" requirement. Seriously, with the low limits, just demand no aftermarket cans, or something like that. Or even sled must be newer than 2015 or so... They're certainly not saving the world by limiting snowmobiles when 99% of emissions pollution comes from maritime transport and industry in general... The park animals that use the roads are completely indifferent to the presence of any kind of traffic, regardless of season, they didn't need to do a 15 year study to know that, they only had to pull their heads out of their a$$es and look around...
It's been more than 10 years since I was in the park in the winter, so I'm planning to check into a snow coach tour while we're there this year. I'd much rather do my own tour, but I don't ride a brand new 4-stroke sled, and our friends had a terrible experience with a rental outfit tour, so snow coach it is...
Regardless of all that, West is still my favorite place to be and to ride in the winter. If we could afford to move there, we would...
