The "dirt road" where we were dropped off was an "overflow" parking area as we arrived late in the day and the regular parking lots were full.
The "safety issues" is the fact we were left in the dark.... complete blackness, to find our car. My friend was livid over this! No safety issues regarding rides or how the park was run.
And yes, I "cringe" over visiting there because I simply don't like parks with animals. Personal taste issue...nothing more, nothing less. (I'd cringe over returning to AK, too.)
