Of course I was unable to offer TNF much of a solution to the problem, but the dash passes sure seem like an antiquated system. As for enforcement, I occasionally see a TNF employee driving through the camp loop or parking lot, looking for blue passes, but unless he actually walks up to my vehicle there is no way to determine if my pass has been properly marked for the day of use. It is likely that his schedule for the day simply does not afford him the time of walking to each vehicle, as he probably has a thousand other tasks to tend to before his day is done.
So my point is this, these dash passes rely largely upon an honor system, and the monies derived from the passes are used to maintain and improve our facilities so that we can continue to enjoy them. So when we don’t pay the appropriate fee, in reality we are only hurting ourselves. So even if you have forgotten to scratch that pass, throw it away for after all, it is not an unlimited pass.
