Tom, compared to facilitating and presenting the effects of PHC / restoration pruning /root invigoration over time, rigging down chunks of biomass is like watching a thick coat of paint dry. And, one leaves a growing tree, one leaves a boring old stump. It seems to be a newbie thing, as in the first decade or two of climbing/removals thinking that's the criterion of "Real Tree Work".

X2: "Passion is key; Energy is important; Humor is a bonus; Tell a story and connect with the audience. " and "I try to stay willing to laugh at myself.

I'm used to powerpoint, now Keynote, and am just scratching the potential audiovisual surface. It's fun to move animations, video etc in and out as today's technology makes possible. Used to going without the Notes function, but am filling some in now as senility creeps in.
Skipping Portland, only the 2nd missed ISA in a decade, due to a local mtg aug 8-10 and trips to Canada in september, France in October (the triennial Intl Oak Soc conference--come on over to Bourdeaux!) and China (hk chapter) in November, and ASCA in December. whew. Have fun!
And to start, the ISA site has good free ppts, as does gilman's site. I think you can still use these as templates and mix in your own examples, visuals etc to bring it all home. As long as the user is more in control than the technology, it's all good.
