A very nice place for a relaxing afternoon while in Greeley, Colorado is the Poudre River Trail. What you need to do is meet with a couple of friends, roll, light smoke, rent a couple of bicycles and slowly make your way through this amazing route. After making your way back, check into Texas Roadhouse, a typical Colorado sport bar that serves great food, maybe get a couple of beers. If you decide to spend the night, get a room at the Holiday Inn Express, a place that is always clean, with decent prices, breakfast and fast room service.
For both recreation and activity the best spot is Glenmere Park. However, this option is kind of dull if you don’t plan on being active and just want to sit down somewhere and get a good view while you smoke. If that’s what you are looking for try out Bittersweet Park. I would say that overall that place has the best scenery and views. There are plenty of places in the area to hang out and smoke for a while, and enjoy yourself. Also in the downtown area, there are many different gift and specialty shops, and you can smoke pretty much anywhere outside in the area. All depends on what you want to do.
