Tire plugs are a life saver, and life taker, your choice, plug it to get home, then buy a new tire, I'll plug a car tire in a heartbeat and leave that sucker in there for life, bike tires totally different..... again, your choice.
I went to Ark last June, 1st day of the 4 day vacation got a nail in my rear tire, no one had a michelin in stock, so my ride for the next few days was slowed right down instead of being up with my friends........
