I work at REI Tustin so I just give the clinics at that location. REI in Huntington Beach gives clinics, also, but I'm not sure who is presenting there. REI tends to use employees at their work location to present clinics, but we ocassionally go to other REI's if they don't have a qualified presenter or if their presenter is ill or is unavailable for that evening. I might add that we all cover pretty much the same information, but tailor the presentation to what we feel our attendees will want. Mine is a PowerPoint that I created using my own photos and material that I have gathered over the years.
Thanks for the invite to this site. It's very well done!
