That is totally okay! There is no rush. I really appreciate you doing this.

Oh that is excellent! How long have you been doing it? I'm assuming these are the not the sort of rafts you stand on and pole along...? (I tried a google image search but there is quite a lot of variation)

That sounds really fun! It is good to have friends you've done trips with before - I've had some disastrous hiking trips with friends who hadn't hiked before and we just didn't gel as a group-doing-a-strenuous-activity.
