Recently, I've started exploring some cardio-challenging trails available in the Twin Cities area. Lebanon Hills Regional Park is a a true gem, with rugged, hilly trails that make you feel you are deep in the wilderness while still in a relatively urban area. I understand that there are around 14 miles of hiking trails, but the photos here are from only about 4 of them ... it's still too early in the season for me to have stamina for anything more. :)
Enjoy your parks. Just think, if the evil government hadn't collected all those tax dollars to preserve this area some private developer could have turned it into a series of mcmansions! With built-in gyms and high fences to keep you out.
