I encourage you to read all you can. Get a subscription to Llamas Magazine and Llama Banner, both of which are both informative and entertaining. LANA contributes a lot of money to research and has an annual Expo that is an excellent training school for both new and old llama folks. Joining groups is a good opportunity to learn from people who have been in the llama industry many years, through good times and bad, and are still positive about llamas. Their feet, composed of soft pads with two toenails, impact the environment less than the boots of an average hiker, yet llamas are strong.
Llamas are efficient foragers.
They have less impact on plant life than the native deer. One or two pounds per day of grain supplement is the only requirement in the wilderness. Llamas are also easy to transport. They travel lying down, so a small, partially enclosed pickup truck with racks or a mini-van will transport two adult llamas. Llamas have discreet bathroom habits.
