My spouse and I recently attended a Renaissance Festival at Sunset Park. I am a manual wheelchair user who can normally wheelie well enough to deal with grass. My chair is an ultra lightweight model meant for active use. Unfortunately the grassy areas at this park were completely littered with dips and potholes, which were largely hidden by the grass itself. My best guess is that this might be the result of multiple temporary structures being staked down over time for different events. And/or maybe it’s worse right now because we’re just getting out of monsoon season. Either way, I could not self-propel more than a few feet through this grass. It was even difficult for my spouse to push me, because we couldn’t see all of the hazards. At one point we swerved to avoid a visible hole, and ended up in a hidden one. The pavement was very well maintained and spacious, and the dirt path was also flat enough for me to navigate on my own—for the most part. I used up so much energy in the grass that I ended up needing to be pushed sometimes even in these “easy” areas. I did see a couple people with powerchairs who seemed to be doing alright, though I don’t know what models they had, and I’m not sure if I saw them in the worst parts of the grass. I don’t have a freewheel, but I don’t know much it would have helped. The holes were big enough to cause problems for my back wheels, not just my casters. If you just want to check out the park itself and don’t mind sticking to the pavement and dirt paths, and if you’re okay with some uphill portions, I *think* it should be fine. We didn’t get to see the whole park because we were so exhausted from dealing with the terrain. We did get to sit and watch all the birds at the pond for a while, which was nice.
