then on any day whenever, i’ll drive 30 mins south of here to hit up lake maria.
that’s 66 state parks. i didn’t include the state recreation areas, but i have a tweet in to them to see if those need to be included to be a passport completer (i have a feeling you do need to visit them). i did include one recreation area because i want to see if it’s good training ground for ragnar: cayuna country up by brainerd. 
i’ll need to camp during a couple of these! probably all of them except for the ones where i’m visiting people at the same time. depending on the time of year, i might have to plan ahead on some of these. the north shore state parks probably fill up quickly during the summer months. 
but seriously, this is 5 trips, 2 of which revolve around visiting people, so only three trips to hit all the state parks? i can deal with that! and if the first one is too much, then i’ll split them up. but even if i take off a friday or monday and spend two nights camping, that works for me. i think i’ll have to find a less complicated tent to sleep in.
plans for all these? i don’t have to spend a lot of time at them, but i do want to get a photo of the entrance sign and need to get a stamp at the office. i’ll probably spend a little time at some of them and not a ton of time at others. all depends on the park!
