I built this tool because I was genuinely frustrated with the "planning tax". Every time I wanted to plan a trip, I ended up with 20+ tabs of climate charts, airport distance maps, and "Best time to visit" listicles that were 90% ads and SEO fluff. I just wanted a way to filter the 63 parks by hard data: Transit time from the airport, optimal weather windows, and stargazing quality. I shared an early version of this on Reddit last week and it kind of blew up (60k+ views in a day), so I spent the last few days cleaning up the UI and adding features the community asked for—like the "avoid these months" data and local browser storage for your favorites. A few things about the tool: * No BS: No ads, no paywalls, no tracking. * Fast: It runs entirely in your browser. * Open Source: You can check out the code on my GitHub (linked in the description). * Logistics-First: It calculates the actual slog from major hubs (LAS, SFO, etc.) so you don't book a "quick weekend" to a park that's an 8-hour drive away. I’m looking to add permit deadline alerts or crowd density data next. I’d love to hear what would actually make your trip planning easier.
