theres like 5 sd threads but i'll entertain this one. heavily depends on what part of the county you're gonna be in and what your transportation situation is looking like. i used to live right by linda vista park so this is gonna be my recs for the the zone between the 56 freeway and downtown, also im vegan so bear with me on the food recs but they're really good imo.
curbs:
-tecelote trolley station, really fun and right off the 5 freeway
-liberty station, theres a good parking lot with really fun curbs by the point loma nazerene building/holiday inn in the back
-downhill curb under the 805 off of friars road
-la jolla curbs, not sure if this spot is valid still but it's indoors right by the utc mall
skateparks
-city heights
-shelltown (national city) - really slippery but pretty fun tbh
-pacific highlands ranch, fun little skatepark in the front, pumptrack in the back (pause?)
-del sur skatepark
-rancho penasquitos park
-poods in encinitas and luecadia (north county but so fun)
(vegan) food
-plumeria thai-normal heights
-donna jean-hillcrest
-sipz-north park DO NOT go to the clairemont location
-plant power fast food, any location of your choice
-tacotarian-north park
-grains-normal heights
