So far Nicky has had all the fun with the cache hides. Now his mom gets her chance. She highly recommends that you get this during the wintertime as all the thorns are just babies right now. I would tack on another 0.5-1.5 in terrain difficulty possibly from Memorial Day-Halloween.
As for parking you can park by the soccer fields at the school on the weekends or nearby at the basketball courts while school is in session. Please do not park and walk on school grounds while school is in session.
BYOP and re-hide as you found it.
