Photography in Ames?

Hey y’all, I’m new on campus and looking to keep going with photography, just as something fun for the weekends. I used to shoot at state parks back home, but I don’t have a car on campus, just CyRide and walking. I was wondering if there were any local nature preserves or nice parks within walking distance from a bus route. I couldn’t find anything super solid on google maps, so I thought I’d ask. TIA!!
