Well, when you say "long rides" you may mean 'long waits". The ride to the park is no different in a bus or a car. But you can just get into your car and drive there, then park a mile away

and walk or shuttle to the park (
plus parking costs). The bus sometimes requires you to wait for the next bus, sometimes up to a 20 minute wait, as it's just like a city bus stop and buses to different places come though all day, but there have been many occasions where some buses don't show up for a while. If you are not in any hurry I suggest just taking the bus...it's easy.
