Andy can appreciate the complications of trying to work out while on the road as he travels much.
On my recent week in southern California I was pleased (for a change) with how much I got done.
The following day had my best stint, a trail run to Lost Palms Oasis, Joshua Tree National Park. Ran fairly hard 7.5mi with a side scramble of Mastadon Peak. Later that afternoon somewhat ran out of gas trail running Ryan Mountain Trail in the Park.
Most fun in Joshua Tree was bouldering. Not quite as good as Red Rock in Vegas, but similar.
