Serious question:
Relative in town for brief vacation wants to do a shallow drift dive on spring-fed river.
Schedule is getting squeezed, and the only opportunity may be the morning of her departure.
Deepest spot on this stretch of river is about 21 feet. Average depth would be 12-15 feet for about 45-50 minutes. We'd be out of the water by 10:00 a.m. Her flight is at 7:00 p.m.
My inclination is to adhere to the 18-hour rule, even though the opportunity for nitrogen loading seems negligible, because I'm not comfortable with deliberately planning to deviate from published standards.
Is this the correct response, or would that be too persnickety?
