I leave a fair amount of time for questions as there usually is a lot of them. I do give my email address as well for those maybe too shy to ask a question and for those that wish to let know how their walk went.
I really enjoy this very much as my wife and I have gotten so much reward and satisfaction from our six walks. We are doing the Del Norte last September this year.
Any other questions, let me know.
I use a power point presentation as the basis of my talks. I am fairly selective on how many slides as past 75 or 100 people's eyes start to glaze over! I do take my back pack and unload it to show what I take. I typically dress as I would on the trail as well. I have a binder I pass around with my credentials and five compostela's.
