One of the things I love about Los Angeles is how close everything is. Within 5 ours of my house we have skiing, white water rafting, deserts, mountains (including the highest mountain in the continental US), ocean, lake, hot springs and goodness knows what else. Around LA alone there's over 4,000,000 acres of hikeable wilderness, which gives me a lot of choice when it comes to picking where I want to go. Even better is that the majority of Angelenos seem to stick to two hiking trails- Runyon Canyon on the East side, and the Pali loop on the West. Which means that on quite a lot of days, even though I live in one of the biggest cities in the world, I have a place entirely to myself. If you stay in the city, you'd have to look really hard to see that the seasons are changing, especially when we're hit with 98 degree days in the middle of October. But if you get out, even a few miles out, you can't help but notice the effect the hot, dry summer has had on everything, and notice that the ground is covered in leaves and acorns, and that the sun is lower, the light longer and the air has a bite to it that wasn't there a few weeks ago. It's much more subtle than the East coast fall colours. But I love that about deserty places- the subtlety of everything except the landscape itself.
