I traveled to Ontario OR for Free Museum Day, 9-18-2021. I wanted to explore the Japanese Gardens at the Four Rivers Cultural Center, to add to my Japanese-American Journeys post https://www.travelpacificnw.com/accessible-travel-blog/japanese-american-journeys
Imagine my delight when I found out that the very same day was an hispanic fiesta celebrating Mexican Independence Day! Then when I got to Ontario, I found another bonus: the Tater Tot Festival was that weekend as well! You could start that Saturday at 9am with the Saturday Market at the historic Train Depot park.
I wanted to be sure to get a parking space at the Cultural Center, so I found where it was the night before, then got there early Saturday morning, and actually had time to explore around town a little before parking at 10am when the Four Rivers Cultural Center and Museum opened. I loved that they were showcasing 5 cultures of the valley, beside a little natural history. First I went through the Museum (a few highlights below). See also https://4rcc.com/

With an hour and a half to spare before the Fiesta started at 2pm, I decided to see if I could wheel downtown (perhaps about a half mile) for the Tater Tot Festival. The terrain is flat, major streets have sidewalks with ramps, people driving were very thoughtful and patient as I crossed the roads. See also

I got back from the Tater Tot Festival downtown just in time for the fiesta at 2pm. By 3 or 4 pm it was rather windy and stormy, starting to sprinkle, and as I was worn out from treking around town, I went back to my room, thinking it was 5pm and all was over. I think I got the time zones mixed up, so I must have missed the dancing, which I would have enjoyed so. But as the weather deteriorated I was so very glad I didn't wait to go see the Tater Tot Festival, which I had intended to do after the fiesta.

I've been in a wheelchair for 30+ years. It poses some challenges for traveling. Maybe others can benefit from my experiences.
