Do you routinely use 4wd or seldom on your Foreman 500? Under what circumstances have you had to go to 4wd? I have a new Foreman (my first ATV) and wanted to get an idea of how capable 2wd is and under what conditions I should be thinking ahead about 4wd before I get in a situation where I am wishing I had put it in 4wd. From what I have read, it sounds like 2wd is usually enough except when it gets real bad. Thanks.
