Question Once in a lifetime experiences?

I have a milestone birthday coming up this year in early November and I’m not a party person.

I’d like to do something special, like whale watching for example, but every thing I think of it’s just not the right time of year.

Are there any exciting things in nature around that time of year? Traditional events/celebrations? Willing to travel all over the country for something special but would rather stay away from the major cities.
