As a trail builder who likes clean forests, f*** course tape, that plastic ribbon has a way of sticking around forever. I'm talking in generalities here, not necessarily WCDH, but I'd like to see tape completely go away (same with tear-offs). Poles are a better solution, just need to use a wee bit of common sense. Stripe them if they're a caution/jump marker vs course marker. Works for color blind riders and can be done with a handy roll of gaff tape instead of having a separate inventory of markers. Just put 3 black stripes on markers that won't DQ...
