my dad is great for lots of reasons (like driving all the way to waterloo to bring me to goshen for a week (no, not so environmentally friendly, but i am taking the train back), giving support and encouragement, and growing delicious vegetables), beyond that his commitment to environmentalism and sustainable living is really inspiring. he bikes or buses to work almost everyday, buys almost exclusively local produce, mows his lawn with a blade push mower (no gas, no electric), and always adds a few more layers before he turns up the heat. recently he made his commitment more public with his company Hertzler Systems. they planted 600 trees on their land in the industrial park. you can read a great article here and see some pics!
