Bringing my Mandolin this year for Telluride and was wondering if anyone had tips for instrument care with the temperature fluctuating so much between day and night as well as any effect the altitude may have on instruments. This will be my first time in Telluride with an instrument and I want to make sure I don’t damage it.
Good case, when not playing day or night keep in the tent, if its night and your not playing keep it in your sleeping bag, bed.
Use a humidfier of some kind in your case and keep the sponge part moistened daily or when needed !
Dont get drunk and forget though
the classic move of getting to f’d up and finding it leaning against a cooler or chair in the AM 
i know all too well
i can tell you what not to do. Dont leave it in a tent that gets hot during the day, Did that last year and the binding came off my guitar. Better to leave it in a case and outside in the shade during the day.
I found a Martin after RockyGrass one year, I turned it in to the Planet…hopefully it found it’s rightful owner
