Wedding theme ideas?

B

So, I'm getting married in June 2019 (I know kinda far away) anyway! We need to start planning here in about 6 months. We have the place we wanna get married at and the colors, but I need help with like the theme for decorations. We plan on getting married at this place called Golden Mountain Park (it's an off-road park for jeeps, rock crawlers/bouncers, etc..) Any ideas?! Colors we want are Burgundy and Grey. (Also this will be outside)
