Variable Star eh? Never read any Spider Robinson before that, but picked it up to read just... one... more... Heinlein...
You could feel his writing in it, but it was artfully mixed, seemed to me like Spider Robinson did a good job integrating Heinlein's voice with his own.
To be honest, sitting by the fire is one of the big reasons I go camping, so I don't use a stove most nights. I usually set up my days so I have plenty of time to cook/sit at leisure by the fire. So I usually carry a alcohol stove + fuel for backup, or sometimes an esbit stove.
Alcohol stove and alcohol (and fuel I guess..
squeeze bottle of tabasco.
