There are VERY few gay or black customers of REI.
Outdoorsmanship is a straight white avocation in the main, in my experience.
Q: Are there any statistics showing rates of participation in outdoor activities like hiking, biking, skiing, etc. by race and hetero- versus homo-sexual?
A: Via Grok (selected bits)
Participation rates (% of group that participates):
• Asian/Pacific Islander: Often highest (~58–59% in some years).
• White (non-Hispanic): ~56–57%.
• Hispanic: ~51–56% (strong growth in recent years).
• Black/African American: Lowest overall (~38–41%, though increasing; e.g., +5% in one recent year to 40.7%).
By Sexual Orientation (Heterosexual vs. LGBTQ+)
• LGBTQ+ individuals consistently show higher participation rates than heterosexual/cisgender adults. They are described as “the most active adult cohort.” 
• In recent reports (2022–2024): LGBTQ+ participation rate >60% (e.g., 61% in 2022), vs. lower for heterosexual cohorts (e.g., ~50–60% for cisgender males/females overall, with heterosexual women often lower).
• Bisexual individuals often highest (~65.6%).
• LGBTQ+ make up ~11–11.4% of the outdoor participant base (19–20+ million people), higher than their ~U.S. adult population share in some estimates. 
This holds across activities like hiking, camping, paddling, etc.

So I was wrong about gays.
Yeah but REI is called a co-op and a lot of liberals drive their Subarus over there, white though they may be.
