A lady out in Colorado has a post that says very succinctly why I bother tromping around with my kid.
The paragraph that caught me was:
"Yes, hiking with kids is more difficult than hiking without them. Yes,
they walk slow. But the answer to successfully hiking and backpacking
with children is simple: Start them young and be patient."
"I Walk Slow" by Backpacking with Kids
It's worth reading the whole post. (I enjoy all her posts, but I couldn't not share this one.)
