We took our first October trip this past fall to celebrate my birthday.
We were there on my actual birthday, and it was GREAT to be in my favorite place on Earth on my special day, but it was much more crowded than I expected it to be. The weather was nice--not too hot, but warm enough that when we got soaked on Kali at AK we weren't freezing. We had a VERY rainy morning one day, but around 11 am the rain stopped and it was overcast the rest of the day. We just donned our ponchos that morning and shed them once the rain stopped, and it was the only time we needed them the whole trip. It was a good trip in all, but I was disappointed to see such big crowds at a time I expected to be a little slower.
