It's awesome, we have the biggest Parkour community in the country, along with two fantastic parkour-dedicated gyms,
APEX Movement. The weather is pretty nice, we have over 300 days of sunlight a year. Hot summers, decent winters, the mountains are amazing and have endless opportunities for nature exploration, or any outdoor activities, snowboarding, skiing, rock climbing etc. Denver is a good size city, not huge but just right. The people are pretty friendly as well, there's a good amount to do.
