Dillon
Is an awesome town in Montana, that we stayed at on our way to Glacier and on our way back. If it wasn't 5 hours away I would buy a house and spend my summers here. They have some really Great old houses. not to mention a few surrounding ghost towns to visit, which we did last year.
Oh yes we happened to be in Dillon for Montana Days which had a Rodeo!
And our favorite RV Park "Southside" Love this place so friendly and very well kept up! And with in walking distance of restaurants and stores.
They also have plenty of room to maneuver big trailers into their spots.
