We send our kids to a public school in the neighboring town, so riding is out of the question except for a few times each year when I have days off and the timing works out. 3rd grade and preK. The younger is proud as can be to roll up to school in her WeeHoo.
Growing up, I rode the .8mi to elementary school starting in 2nd grade and did it every day that was dry and above probably 50degrees in the morning, so maybe 1/3 of the school year. Did it thru middle school too riding 1.5mi. We used to ride all over the burbs each summer getting into semi-trouble for miles and miles each day.
Now? I cant imagine my kids riding around unsupervised like I did. I don't trust drivers- way too distracted in my eyes. Hopefully as they age, ill grow more comfortable. The 3.5mi ride to school probably wont ever happen on their own though, just too far.
