Bruce,
Yall may have beat this one up already, but having been a ranger / RT, the only policy we had to enforce was that every member of the crew must sleep in a tent. (I.E. No bivys, hammocks, or sleeping under the stars…) This rule is directly due to bear protocol / insurance risks for the ranch. Â As you mentioned, we look at clusters/LNT when passing through sites. We also ensure that there are no lone tents.
No ranger should be giving any of your adults or scouts flak for choosing a solo tent. (If so, seek out someone in Ranger leadership at base and call their bluff.) If it were me going back again, I’d use a Tarp tent MoTrail or split an MSR Hubba Hubba Nx with another adviser. Both are great and on the lightweight side. Also some good stuff mentioned above for Six Moon and the BD Megamid. The ranch has a pro deal with MSR now and issues the Thunder Ridge, which is really beefy, but also unnecessarily heavy. I’ve led crews with advisers sleeping in each type of tent and both have their own pros/cons.
Like Matt and Ed both mentioned above, all the shelter issues will get smoothed over during shakedown (& as you’ve experienced already.) I’d probably be weirded out as a ranger if an entire crew showed up each with solo tents, but I’m not aware of anything technically prohibiting that.
Whatever you wind up sleeping in, it’s Philmont – you’re gonna have an awesome time! IWGBTP!
