For those of you who desire pure and utter brilliance in a certain form I've this to say.
Get yourselves a sea kayak
The reason being that;
the people who like physical geography will be delighted seeing the classroom material being brought to life.
the people who like excerise will get just that, plus fresh air.
the people who desire to see natures physical power will be in awe.
the people who meditation or need to chill out in pure peace will contact the heavens.
The people who want freedom will be immancipated
All in all getting out into the sea is a brilliant experience. THose are the few things I have seen and experienced. Not all of those things will appeal to everyone, but I've covered a big bit of people I hope...
