That means I can no longer use a different notebook or workbook for every subject, particularly as my surgeon has limited me to lifting 20 pounds for the rest of my life. (Had three hernia surgeries and would prefer my intestines stay inside my body from now on.)
So I've torn out all the workbook sheets and stapled them into weekly "packets." When I'm getting ready to leave for the college, I'll put the relevant packets in a hard folder, grab our LIFEPAC science workbook and our pencil case, and head to the van.
I bring sandwiches and we have a "picnic" before heading in and grabbing a table. Rewards for good work mean the children each get to pick out three books and on particularly long days, they can use the kindle for a little bit before heading back to pick Patrick up for the drive home.
When I'm feeling particularly adventurous, I'll pick a restaurant that looks homeschool-friendly. The problem is that we need to stick around for several hours. McDonald's is friendly, as is the local Taco Bell. I had never been in a Taco Bell before and doubt I will go to another again (barring national disaster and so forth - never say never). We've also done the coffee shop thing a few times.
