If you're like me, you have a lot of nature trails near your house. If you're not sure, check with your local conservation center. Don't let the fact that you don't know the route be an excuse not to go. You can always turn around and go back instead of making a loop! Go with a friend the first few times. It's easy go a little farther each time because you're excited to discover more :) Bring a camera along in case you see wildlife or if you're in the right location, hunt for fossils :D
There is a lot of information on SparkPeople and it can become overwhelming if you let it. My advice is to take your time and explore a new area every day. This is an awesome tool...don't let yourself become overwhelmed with all the information.
