I've been reading about many people being prone to altitude sickness in Breckenridge. We are going to travel there in November and didn't want this to be a factor. However, we've been to Ruidoso, NM and Ski Apache numerous times with no problems at all, but nobody ever complains about altitude sickness in New Mexico.
In contrast, Ski Apache is at a higher altitude than Breckenridge. Is there something I'm missing? We should be fine in Breckenridge right?
